A widow without perma-mind link or softcapped anything isn't likely to live very long. Usually widows are built well above the softcap because of their weak ddr and lack of resistance. Not sure aura of confusion would be enough mitigation to save you. I'd link my fort build but it's highly specialized for exemping and wouldn't really help you given your wanting to emphasize psi attacks. Mine's built to have softcapped defenses and sub 4 second follow up, lunge and spin at 25 for silver mantis solo merit farming.
You have enough slots to play with (lose the 2nd slots in vengeance and tactics, the 3 piece prestige sprint and the 6 piece efficacy in stamina, i'd replace the latter with 4 perf shifter) to get perma-mindlink, and positional softcaps, but only if you dump one of the travel powers for a two slotted hasten (which would end up a half second off perma), switch 3 aegis pieces into indomitable will for the non +3% defense pieces, and 3 slot botz somewhere. With the extra slot that would leave I'd go ahead and throw the 6th coercive persuasion piece in to give you an extra 5% ranged def to help a bit with ddr.
