Greater enlarge person (not the SpC one). Balanced?

If we use expansion as a precedent, it should be 4th level. But between that and +8 to grapple as an immediate action using gloves of titan's grip, psionics gives +16 to grapple whereas in core you can't get more than +4. It's nutso. A psychic warrior grappler can grapple 80 foot long purple worms like alligators. In terms of stats going up in size is almost break even. It's the grapple, tripping and reach that really matter. You should mention the space and reach of a huge creature like the original: 15 feet and 15 feet.

Assuming you allow psionics and a little bit of power creep, it's fine at 4th level. It should apply only to humanoids or gargantuan creatures could do crazy things with it. True, expansion affects any race, but at least it has a personal range. Crazy races becoming psychic warriors must pay LA & RHD, which delays the 2 size category and swift action expansions. And a humanoid target imitates the regular enlarge person. I'd also allow it to be made permanent with a permanency spell, at the cost of 2,000 xp.
