One can dream, right? I was just thinking what I would do to this panel given unlimited funds....
Throw away the old transponder, you'll need a mode-s one soon anyway (most likely). Mount a modern Com/Nav/GPS in that corner.
Throw out the CDI at the bottom right, mount the RPM indicator in that corner.
Move the ASI to bottom left and mount two AV-30s top and bottom instead of current ASI and AI location.
Use a TailbeaconX to cover transponder needs (controllable from the AV-30s and includes ADS-B and such).
Mount the fuel computer where your current radio sits.
That should leave you with a lot of new gadgets with plenty of old-fashioned backups to fall back on. Old-fashioned look will still be intact.
Edit: I'm sure there are some illogical choices in there.... but I said I was dreaming...
