metaphysics and psionics

[AZRAEL66]

can ghosts (template, mm1) use malevolence and manifest psychometabolism powers from the host body? can they learn those powers in the first place?

how about items that grant the ability to cast psychometabolism powers?

I'm thinking of a body-fuelling ghost psion that keeps blasting enemies with the host's own burned ability scores. too bad they capped body fuel to 60.

Ill attempt to answer this... please tell me if im wrong...

malevolence (magic jar) snags you the target's body, and with it, the creature's physical attributes. since the ghost is now a corporeal living creature, because of the host's body (for a while) it now has a metabolism, thus subject to psychometabolism powers. everything affects the host now, not the ghost, so he can heal the host's body with body adjustment, grow claws and fangs, etc. Is this correct? the rules don't actually cover everything about the ghost template.
