This is REALLY COOL!
I really like the "Epic Recharge Time" you introduced (never thought of that) and the Martial Lore prerequisite (now I better understand what you intended).
IMHO this Manuever seems a little too strong for his level, but that's mainly because I consider 10th level Maneuver to be learnt by 21st level Martial Adept (whilst your Martial Lore prerequisite sets the minimum Martial Adept level to 25).
My intent is to create beyond-nine-level Maneuvers that can be easily learnt and used by newly-epic character.
Regarding your Maneuver, I'd move it to level 11 or 12 (therefore restricting the access to level 25 or 29 Martial Adept).
The Recharge Time is an interesting feature: I take a little time to consider its introduction.
Sorry for the double post...
