If so, I am leaning towards retaining my OE (new) bushings coupled with the CF propshaft. Do you think there will be any issue with using this CF propshaft with the OE (new) bushings? Are the OE bushings robust enough to deal with the more direct force of the CF propshaft? TIA

I had solid aluminum subframe and delrin diff bushings and had significant (for me) whine. I swapped the delrin diff bushings out for purple PowerFlex polys and the diff whine is basically back to stock levels, but the rear end still feels rock solid.
For max performance, aluminum subframe and either delrin or aluminum diff is probably your best bet. But for keeping NVH to a minimum while still vastly improving rear end stability, aluminum subframe and PowerFlex purple is the ticket.
