Cerebre - Meta - Magic ... whew that's a mouthful!
From Dragon #349 -- and a personal fave.
It's complicated enough to need the whole thing to make sense of it.

You can metamagically enhance your spells with your mind.
Prerequisite: Any metamagic feat.
Benefit: Choose a metamagic feat you know. You can expend power points to create a prerequisite spell slot needed to prepare a spell modified by that metamagic feat. The power point cost equals double the needed spell slot's level (the level of the spell needed to prepare or spontaneously cast the desired spell with the desired metamagic feat applied). You also must devote a spell slot of the spell's normal level to this spell. You cannot enhance a spell in this way beyond the level of the highest-level spell you can cast. For example, a psion 5/wizard 5 can - instead of using his only 3rd-level spell slot preparing a maximized magic missile - spend 6 power points to maximize the spell as a 1st-level spell (using up one of his 1st-level spell slots to do so). A sorcerer must spend a full-round action casting a cerebremetamagic spell.[/spoiler]

OK ... this is ridiculous ; ridiculously awesome. There's no reason to pretend at all.
"psion 5" is not a limit.
6 powerpoints are being spent. Hello.
At low levels it is expensive, perhaps too expensive without massaging.
You need the original spell slot , the metamagic feat , a 1 level psi dip ,
and 2 x spell level of the target "slot" spell level in ppoints.
That last one sounds kinda complicated but the example explains it well enough.
Level 1 spell slot + level 3 spell "slot" of powerpoints = mission accomplished.
Let's take a basic dual caster build:
Cleric 3 with Heighten + Persist and support, but no DMM
Ardent 3 with the Cerebremetamagic feat, otherwise boring.
With regular bonus powerpoints for high Wis, the pool is around 18 (or so).
I'm just eyeballing this.
You could Heighten a level 1 spell to level 9.
You could Persist it then. (miracle at level 6
lite going on here)
You use the powerpoints to pay for the Persist. Ta-da.
It gets worse (better!) from there.
Heighten / Persist all and I mean
all your spells.
A little psi Recharge goes a long way, eh ?!
Cleric or Wizard 8 / Ardent 2 / PT 10 and 3 or 4 feats = silly.
... ideas ??
