I suppose you could try to lower the level of Time Stop via stupid tricks (Sanctum Spell, metamagic reduction below 0). Alternatively, Craft Contingent Spell (hideously borked, but whatever) doesn't seem to have a level limit on the contingent effect. Also, you could have 20 of them.
Moment of prescience (possibly made contingent via tricks or CCS, but you can also just cast it in advance) could probably give you +25 to your initiative roll (I think initiative is technically an opposed ability check). Foresight can prevent you from being flatfooted. Eager Warning // Spellstrike Defending Quarterstaff w/ greater magic weapon is +7 (and various other bonuses.) Shapechange into a Gloom is +18 more. Shouldn't be too hard to get more than +50 on your init check.
Another suggestion is psionic contingency + anticipatory strike (or indeed synchronicity). You can easily hit the UPD check to use the dorjes (even with 1 rank, limited wish for divine insight is +15, plus a rank, plus 3 CHA (Eagle's Splendour, if you need it) is +19.) I actually think this might be the best method of all.
