I'm thoroughly convinced that your solution lies with making your character a warforged metamind with temporal reiteration that has kept its font of power active for 100 years, while maintaining its body with its own psionic abilities.
Using temporal reiteration for free font of power time seems pretty cheap. I mean think of the applications to any time power. Use it with temporal acceleration to have infinite timestop (only while warforged). Use it with fusion to infinitely be fused with and in control of your cohort, doubling your HP/PP/etc (say you are a warforged fused with an elan, you're nigh invincible). Do you even need to sleep if you're a fused warforged/something else? Effectively all of your powers are affected by permanency so long as you don't use more than 10 swift actions using temporal reiteration. Although it seems completely legal RAW, it is still cheap as hell, but isn't that why metamind is a 10 level prestige class for psions that only has 5 +1 to manifester levels in it?
You could probably also have 1 copy of yourself running around by using fission. They too could have their font on indefinitely so long as they don't need to sleep or rest. That would nearly double your damage as a character(s). Now imagine if you and your cohort were both metaminds with fission and reiteration, you'd have 4 characters, and would effectively be a 4 person party all by yourself.
What the hell was WotC thinking when they wrote reiteration, so much that I completely want to try playing a char with it.
