You can't get a 53/39 Chorus 12 crank, but there shouldn't be a problem with a record 12 crank and probably no problem with an 11 speed crank. Chorus offers 53/36, 50/34 and 48/32 cranks.
The chorus 12 shifting shifting is excellent. If you don't want to spend a lot for the campy chain tool, a cheap park tool will work to shorten the chain. A kmc 12 or sram eagle quick link will join a Campy chain. I find that the sram axs 12 chain also works and is quieter.
I have the 48/32 with 11-34 cassette.
