Well, one thing you need to remember about the P-47 was that just about every mod that was put on at the factory, except for the bubble canopy, was replicated in the field on older models. By mid-war, there were C models that had water injection, for example. Someone a couple of months ago posted a picture of Jugs taking off for Saipan from a CV and it listed it as a D-11. I stated that it couldn't have been a D-11 since it was taking off with drop tanks. Widewing looked up the serial number and sure enough, it was a D-11 that had been field modified with the pylons and plumbing. So, I would expect that there were D-11's that had paddle blade props installed, as well as some of the other mods that came out, just as most D-25's and D-30's got the vertical stab fillet, etc.
Simply put, HTC models the planes in their factory condition, and not what they were modified to out in the field.
Personally, I'm looking forward to the P-47D-23 and P-47M both showing their faces in Aces High at some juncture [insert mandatory "after other holes in the planeset are filled" disclaimer here].
