Don't think this will work because of the geometry of the nose gear rail 
which is attached to the fuselage and engine mount.  Moving the engine 
forward would also move the rail forward.

 Why not just add a small spacer to the engine mount at the firewall. This 
would
put the whole engine assembly forward a little bit giving you more space 
at the cowl.
After all you probably only need about 1/8 to 3/16 of an inch or so.

Paul,
 
You could consider a plate between the crankshaft flange and the prop. 
However, that might change the dynamic vibration and its harmonics?  Seek 
advice from Hartzell.
 
Can the rear of the spinner be shaved without reducing structural 
integrity?
