Two errors in your build.
1. Max AGL is 11 for an elf with Exceptional AGL not 12[My bad, missed a buried line in BBB -NR]2. The improved Physical attribute adept power requires you spend 2 power points for every attribute point above the natural max. So, that two points of AGL would cost 4 power points. Withthe power point your spent raising Longarms by +2, that puts you at magic 5. Given that you're losing two magic levels to essence loss, you'd need Magic 6 + Initation to pull this build off.
I wanted to see if I could come close to what you had going a slightly different route. This is what I came up with:
