Sounds like you have a long action and no aversion to something a little unusual. My buddy is in the process of building a 6.5 Sherman, which is kind of a 6.5-06 Improved with the shoulder slightly forward. You could look into that if 6.5-06 is too boring...
Sounds like you have a fun project going on.
Cheers,
