I've already ordered a co-ax SMP from CQOUT and I'm very interested to know as well. Also, I'm wondering if the case back from the new co-ax chrono(which I believe is correct) will fit this watch. If I take care of those two things, the only thing left is the movement(don't care), He valve position(don't care), and the 3 o'clock lume marker(don't care, but if I could find a gen dial for a decent price, I'd consider replacing so I could do a logo swap on the co-ax chrono.
