Assassin/Mechanic are generally easier with higher ceiling due to the ease of being Int based.
Could you easily do a wisdom based aasimar acrobat? Sure! Spend 16 or so in Aasimar, capstone in acrobat, then get yourself some tier 4 goodies from the bird tree. Would be nice self healing that recharges, some on hit vulnerable, and good tactics DC's - at the expense of maybe struggling to do traps on the top end without excessive gear swaps. If I were to build one this is probably the route I'd take as the good gearsets really support dex as a secondary stat anyways.
