Help with Losmandy Dovetail System

I am looking for a way to sturdily piggyback a WO Megrez 90 on a 10" LX200. I have a pair of William Optics 90 mm rings, and the hole spacing on the rings is either 30 mm, 60 mm, or 80 mm. I'd like to install the Losmandy DM-10 dovetail on the LX200 OTA and then attach the rings to a pair of losmandy dovetail adapters (DA). However, there is not any information available on the Losmandy website to indicate the hole spacing on the DA's. Does anybody out there know whether or not the WO rings are compatible with the Losmandy dovetail adapters?

I also have a Vixen style dovetail plate, but I don't think anybody makes an adapter that mates the Losmandy dovetail with a Vixen style dovetail.

Any help would be greatly appreciated.

Thank you for the advice. If I have it figured out correctly to piggyback the Megrez 90 using the WO rings, I need the Losmandy DM10 with the radius blocks to bolt to the OTA of my LX200. Then, a pair of Losmandy DA or ADM dovetail adapters, and then ADM's ultimate adapter to go from the 2" DUP hole pattern to the 60 and 80 mm spacing of the william optics rings. I think this ought to do it. I have the WO Vixen style dovetail plate, but it seems that it isn't going to be of much use for mounting to the Losmandy D bars.

I am not loyal to any platform, but I don't see any other dovetail bars with radius blocks that would enable piggybacking on top of an LX200 OTA.
