Let's Make the Dead Stand Back Up! [3.5, Incarnum and Summon Undead Lovin']

[Amechra]

Incarnum Necromancy [Incarnum]
You have learned how to alter the essentia pattern of your Necrocarnum Circlet so that you can overwhelm with numbers rather than with power.
Prerequisites: Ability to bind the Necrocarnum Circlet to your Crown chakra.
Benefit: As long as you have your Necrocarnum Circlet bound to your Crown chakra, you may cast any Summon Undead spell of a level equal to or less than the amount of essentia invested into your Necrocarnum Circlet as an Arcane or Divine spell (chosen when this feat is first taken) at a caster level equal to your meldshaper level.

The summoned undead last until you either unbind your Necrocarnum Circlet from your Crown chakra, you cast another Summon Undead spell through this feat, or you create a Necrocarnum zombie.

Rise Through the Earth [General]
You have learned to cast Summon Undead in a slightly different way, tearing corpses from the earth rather than the nether.
Prerequisites: Ability to cast Summon Undead I, at least one Corpsecrafter feat.
Benefits: You may choose to cast any Summon Undead spell that you have access to as a Necromancy spell; if you do so, you are considered to have animated the Undead summoned with the Animate Dead spell for the purposes of effects, feats, and class features that affect Undead that are animated.

Thoughts?

Incarnum Necromancy, being based on essentia capacity, will allow for relatively high-level summons at low levels. Capacity at Incarnate 3 (when you can first get the feat, assuming you aren't pulling shenanigans to get a bonus feat at 2nd level) is 3 (1 normal, +1 Incarnate 3, +1 Expanded Soulmeld Capacity). It increases to 4 at level 6, but then it doesn't rise to 5 until level 10-11 (depending on when you can spare 25k gp for an Incarnum Focus). Increases beyond that are irrelevant, as Summon Undead only goes up to level 5 for some reason (but in case I'm wrong or you're playing with homebrewed versions of higher end spells, capacity gets +1 at 12th and 18th normally, +1 for Incarnate 15). You can get even higher capacity a few times per day by dipping Cleric 1 for Channel Essentia after taking your 3rd Incarnate level.

Any reason Incarnum Necromancy a) specifies arcane or divine and b) isn't just an SLA or SU or soulmeld effect instead of being a full-blown spell? Being a spell opens up shenanigans and early entry things, not to mention other questions like the save DC, ability to use spell trigger and spell completion items, and other spellcasting-related things I cant think of right now.

Rise Through the Earth is good. I'm surprised there isn't anything like that already.

I forgot about Expanded Soulmeld Capacity, Channel Essentia, and Incarnum Focuses.

Any suggestions on how I can word it so that you are capped at your normal capacity (i.e., just meldshaper level unlocks and class features that increase capacity)?

[Garryl]

... of a level equal to or less than the amount of essentia invested into your Necrocarnum Circlet, up to a maximum of 1 + 1/6 character levels.

[Arz]

Word it as per incarnum feats. Cap would be 4 w/ only 2 feats improving it by one.

Why not combine the two feats? Always found it odd that this was not a necro spell anywho.

Not a fan on this feat limiting you from necro zombie while taking advantage of the casting options. Just go back to normal spell duration.
