I'm wondering if a Chorus 12s crankset and 48/32 chainrings will work with my 11s Record EPS front derailleur.

I've looked into Campy manuals for both cranksets (Chorus 12 and Record 11), and differences are:

1. +1mm chainline for 12s
2. 4,8 and 12,8mm from BB shell to inner side of both inner and outer chainring for 12s
3. 4,5 and 12,3mm from BB shell to inner side of both inner and outer chainring for 11s

The smaller 0,2mm gap from the small chainring to the bigger one on 11s can be due to the 11s chainrings thickness (or so I presume), so all in all differences are almost negligible.

If asking Campy the answer will be a redundant NO, but do you guys think that this will work?

I can't say whether it would work with Record EPS but I did use Chorus 48/32 crank with two different bikes with Chorus 11 speed shifters and derailleurs without any problems.

Yes it works fine. I have run this exact combo without issue.
