Really...why do you have to make this so complicated?
Get an L-2. Providing you have a pure fiberglass fuselage just slap it on the inside of the fuse and be happy.
I have an LS-8. The L-2 is on the side of the fuse behind the wheel. Air traffic control radar reads me just fine no matter what my orientation to the radar. Commercial aircraft that are above me read me no matter what our relative orientations.
