Psychosis and meditation cannot be taken together. Tranquility is a safer choice. But, you are probably looking for crits and high damage resistance. If yes, you are missing Psychostatic Electricity for crits.
What do you mean by paladin? You will use only psi? then maybe fast metabolism earlier .
I think that you can get something better on some feats: Power management, skinner (not used for crafting tactical vest), thick skull (really needed with locus?).
Regarding the stats split, you can limit Intelligence to at least 7 for keeping crafting feats.
It is an interesting build in any case
