My Favorite Swiftblade build in gestalt goes like this:
(Note, I am using martial Wizard which trades scribe scroll and 5th level feat for fighter feats)
Wizard 5/Swiftblade 1/Spelldancer 1/Swiftblade +3 //
Factotum 5/Wizard 1/Factotum 3/Wizard 1
However, it may be nice for you to enter Arcane Archer as soon as possible.
So trading the last level of swiftblade for the first level of Arcane Archer may be nice. You would still have to wait until level 11 to get Imbue Arrow though.
The Arcane Archer + Swiftblade, however, eat through a lot of feats. Martial Wizard helps, but you can also take a level of Cleric of Corellon Larethian and pick up the War and Elf domains to get two feats for free! Of course this means you need more levels of wizard progression to catch up.
Overall, I feel that you can't easily get both Arcane Archer AND Swiftblade into the same 10th level build without giving up the power of the factotum (and extra actions are really THAT good). If you want to plan for later though, you can certainly fit that into a level 12 build with something like
Wizard 5/Swiftblade 1/Spelldancer 1/Swiftblade +2/Cleric 1/Arcane Archer 2 //
Factotum 5/Wizard 1/Factotum 3/Wizard 3
Of course you can also go for simplicity and do
Martial Wizard 10 //
Factotum 8/Arcane Archer 2
Also, get a Spitting Bow. Splitting is very very good for an archer of any kind. Ask your DM how spitting works with Imbue Arrow. It looks like you would double the effect of your spells.
[edit] looks like based on wealth by level guidelines, you should not be able to afford splitting quite yet. Still get it ASAP [/edit]
Has anybody looked into a Bard or prest bard + Arcane Archer? Area affect spells, yes, but more enchantments and illusionary less evoc.
First of all, evocation is considered the least effective way to play a wizard in D&D 3.5. battlefield control/buffs/debuffs/save-or-die roughly in that order tend to alter the outcome of battles more.
I have seen a few builds (non-gestalt) finish an Ur Priest build with two levels of Arcane Archer and thus shoot cleric spells.
I have not seen bard builds, but I assume something like Bard 8/Arcane Archer 2/Sublime Chord 2/Some way to progress Sublime Chord 8 would do ok.
