Well if I go sanctified mind path I would add Magic, Conflict, and my 3rd is Freedom or Time (maybe Chaos). I'd use the Substitute Power ACF (DM will allow 2-3 power switches) to get rid of the Magic mantle's metaphysical weapon power, since it's repeated on the Conflict mantle. Magic fits any powers theme so i'd replace it with vigor or force screen or if no Time mantle then anticipatory strike.
In terms of powers i'm not sure if psionic lion charge will be a redundant pick if I also have hustle. Hustle seems more versatile and practically emulates PLC power, though PLC does give a nice dmg boost when fully augmented especially on crits.
As for non prestige class feats: Link power, leap attack, maybe one of the other leap attack feats that let you dump AC and expand knowledge(don't know what power to take, mebbe expansion?) Any other suggestions or substitutions?
