There is only going to be one definitive answer to your proposed mix and that is for you to try it. keep the percentages low and the mix on a switch.

My personal take on it is that its a mix that is likely counter productive and an aerodynamic dead end suprisingly which there are many. This reguardless of your discipline be it Stunt, Pattern, Scale Aerobatics Or 3D. We all answer to the same Aerodynamics just the popular names tend to change.
