I posted a build I was fiddling with quite some time ago that was basically this same idea, but I've since polished it up and made it more streamline so I thought it was worth posting again. Though I'm not sure where it lands in the tier system or even if it's any good, I'm quite happy with it. It's nothing original, and primarily uses basic ideas like the glaivelock and DMM persisting silliness but it works together nicely I believe.

GithyankiGithyanki come from the astral sea, so casting planar bubble on one gives them a free quickened spell every round.
Also subjective directional gravity could be all sorts of fun in a dungeon.
That Monk level The monk level will be modified with two different ACFs. First, it will be an Invisible Eye monk from UA for Combat Reflexes. Secondly, it will utilize the Decisive Strike ACF from PHBII.
Decisive Strike:
As a full-round action, make one attack with an unarmed strike or a special monk weapon, using your highest base attack bonus but taking a –2 penalty on this attack roll. If the attack hits, it deals double damage (as does any other attack you make before the start of your next turn).
Eldritch GlaiveYour eldritch blast takes on physical substance, appearing similar to a glaive. As a full-round action, you can make a single melee touch attack as it wielding a reach weapon. If you hit, your target is affected as if struck by your eldritch blast (including any eldritch essence applied to the blast). Unlike hideous blow (Complete Arcane 134), you cannot combine your eldritch glaive with damage from a held weapon. Furthermore, until the start of your next turn, you also threaten nearby squares as if wielding a reach weapon, and you can make attacks of opportunity with your eldritch glaive. These are melee touch attacks. If your base attack bonus is +6 or higher, you can (as part of the full-round action) make as many attacks with your eldritch glaive as your base attack bonus allows. For example, a 12th-level warlock could attack twice, once with a base attack bonus of+6, and again with a base attack bonus of +1.
It's an invocation (an SLA), and can be quickened like a spell. Strength is not added to the damage rolls because it is not a weapon. However it is a melee attack and so Power Attack can be applied to it. Whether or not Power Attack can be applied to the damage rolls is unclear and has long been debated.
Here's what I think (though there really is no right answer): Power attack only applies its +dmg to melee damage rolls. "Melee damage" is not defined and so I assume it to be any damage that is dealt by a melee attack. Eldritch glaive is explicitly a melee attack.
Reach for this attack will be
25 ft. with enlarge person and
35 ft. with Righteous Might, but it will have a donut blindspot. With Divine Power persisted, Eldritch Glaive will be operating at a full attack bonus, including iteritives. AoOs can be made within this area and with a Devoted Spirit Amulet to give the Thicket of Blades stance, every movement will provoke one.
Decisive Strike + Eldritch GlaiveA round in combat can go like this if no additional spells/invocations are needed to be cast and no movements need to be made: Hit someone with Decisive Strike as a full round action. Then hit them with a double damage full attack maximized eldritch glaive as a swift action. If anyone moves before your next turn, hit them again with a double damage eldritch blast. Any hellfire damage is maximized and applied to every one of these attacks. Past level 14 eldritch blast will turn into vitriolic blast and bypasses SR, saves, and every attack deals an extra 2d6 acid damage every round. (Some argue that this acid DoT stacks with itself, which if it were true would make those iteritive attacks ridiculously powerful).
Here's some number crunching on EB's damage:
7d6 (base) +6d6 (hellfire) +2d6 (Chasuble) +1-4d6 (Scepter)
Total maximum of 19d6
Maximized: 114
Decisive: 228
Full attack: 912 damage+228 for every AoOif Power Attack is ruled as OK, then the full attack will be increased to
1072 damage.
Persistin'Priority 1: Planar Bubble extended (can't be persisted)
Divine Power
Necrotic Empowerment
Holy Transformation
Greater Visage of the Deity
Shield of the Archons
Righteous Might
Whether all these spells can be persisted every day depends on that last level. If Dragonlance is allowed,
Mystic would provide a second turning pool. Extended and persisted spells are also more turn efficient if you can manage to cast them a couple days in advance. If all of these are stacked, the caster will become a beast in combat.
That about covers it. The rest of my feat choices should be pretty self-explanatory but if someone wants I can clarify anything. By level 15 it has 9th level divine spells and a Dark Invocation, and does a much better job at melee than any straight fighter could ever.
Any comments, criticism, questions?
