My best idea is to machine an interface ring that will hold the silicone wrist seal (like the QCP) that has an ID that fits the Rolock.
I don't like the DGS, if I were to get push together I would probably go with Kubi.
I have a spare set of PU bits for the QCP that I can play with in terms of the modification.

Why would you want/need to do that?
Did you watch the video on the modification? It shows exactly how to accomplish what you are wanting to do with an existing installed QCP PU ring and the Rolock 3 system.
The mod has you:
1. mount the silicone seal to the Rolock 3 cuff ring
2. modify the QCP PU ring that is glued into your sleeve cuff
3. press the combined Rolock 3 cuff ring with mounted silicone seal into the modified QCP PU ring
4. mount glove on Rolock 3 glove ring
5. attach Rolock 3 glove ring to the cuff ring
6. go dive
