KJ2020, for those interested in modding, have you seen good/reasonable after market date wheels for the 82xx, 2813/3804 and maybe the 5583? (I say maybe because the closest I can find has it and the 2813 as having the same dw)?
The native DW position on all of the DGs is identical to the native position of the ETAs. So any DW with Rolex fonts will work on a DG movement, either in the native position (like the Sky-D, the DJ41, the Exp II 42mm, etc.) or as a DWO if the numbers are shifted 1mm left to the Rolex date window position. The Sky-D would be difficult to use a DWO in because of very little room underneath the GMT wheel.
There are plenty of reps that have ETA date windows with Rolex font datewheels. Any of those would work in a DG as far as lateral position but the DG datewheel tooth ring is shorter in height than an ETA so one would have to slice off the numbers disc from the ETA DW and reglue it to the DG DW.

This DW number disc could be pulled off and attached to any DG DW and you have a nice Rolex font DG DW. Or just source an ETA/DG date disc (no tooth ring) from any vendor. I used to get rep DWOs from a couple TDs, not so much anymore. There aren't any better discs short of gen IMO.
