I'm not sure I understand:  The angle to right built into most planes is to reduce the amount of right rudder required on takeoff.  So  why would you want to REDUCE the angle to the right?  Most (or at least many) planes have the engine tilted down and to the right - the down angle is to reduce the elevator trim requirement (nose-up pitch on power application) and the angle to the right is for rudder trim.  One problem, and one that I found with my ES mount, is that Lancair turned the engine to the right, but the rear of the engine was approximately on the centerline.  That put the front of the engine to the right of the centerline, adding a left-turning tendency, the opposite of what is desired.  Regardless, I would suggest that you want more angle on the engine, not less, and I don't think you want to angle the engine up any more than it is.  Having the engine nose-down is probably desired, but that's another discussion.  Sometimes the left-turning tendency is caused by an incorrect angle of incidence of the vertical fin, but of course that is a hard thing to modify.  I think with an engine that big on your 360 you are stuck with that magnitude of rudder requirement on takeoff.
