So these wouldn't feel different enough for you?
....
For me, psionics should not be spells. There may be a few psionics that duplicate the effects of spells, but if you're just going to make it into another form of spellcasting similar to wizard or cleric, you're not really giving us something worthwhile and distinct.
I'd rather you have something new. Example:
Psions gain 4 keywords at first level, and psychic warriors gain 3. Each class has a list of powers, and each power on the list has one or (more commonly) multiple keywords in their prerequisites. Psions and psychic warriors gain more keywords as they advance in levels. If a psi class has the prerequsities for a power they can use it - they 'know' all powers for which they have the prerequisites. When using a power there will be several options. Some uses require spell points, others do not. When they do not, the power level is similar to a cantrip. When they require points, the point cost may be specific for a given use, or follow an exponential progression to increase the efficacy. There would be nothing preventing a psi character from putting all of their psi into one use of one power - expect it might only be slightly more powerful than using half their psi points for a slightly weaker version or one quarter their psi for a more reasonable use.
They'd gain psi points as they advanced in level at an exponential rate, allowing them to burn off weaker uses of their power (with power levels on par with 1st and 2nd level spells) almost limitlessly (like a warlock with silent image or levitation can use them limitlessly) or make more uses of those powerful versions of powers as they advance. Reshape Reality might be the 'Wish' equivalent discussed above. If a psion devoted everything to it they might be able to use all their psi points to make it happen as early as 14th or 15th level... but if they want to use it and still have reasonable other options it will require level 17 or above.
Most class features would have a 'standard mode' and augmented modes that are accessed via power point usage, as well. Soul Knives can create basic knives at no psi point cost, but they can also trick out their blades by spending psi points on augmentations for that instance of their weapons.
As a side note - I would never use the word 'illusion' with psionics, but would rather use the concept of phantasms, meaning things they are convinced they see. Certain spells create phantasms (phantasmal force, phantasmal killer), but magical phantasms would be the lesser cousin of the psychic phantasms.
