This was a late addition to the party, felt like fate to find someone local selling one 2nd hand in the exact length I wanted. They also sold me the King cages too.
Thanks! Will give that a go before resorting to facing. Cranks look a little too chunky but I was drawn in by the range of possible chainring sizes and axels etc.
Might try and find a set of the old Dura ace cranks that look so nice on the Fern builds:
