The only thing would be a truss rod adjust.Maybe?Try heavy bottom/skinny top(09 thru 46)as the heavy bottoms make your 9's sound like 10's anyway.Necks react better to this type of string set also,as the bass side has more tension thereby,putting relief where you want it on the bass side and not the treble side of the neck(ideal is no relief on treble strings and relief on bass strings).How you hold the pick,where you pick,touch and attitude all affect tone more than string gauge.My old self has a hard time bending 10's a step and a half on the strat scale.Robin Trower(I think)uses 8's and they sound like 15's.
