Switch 1 joycon adapters for Switch 2

Leaks say the Switch 2 will have magnetic joycons, but that Switch 1 joycons will be compatible, wirelessly at least. What are the possibilities that a third party (because I doubt Nintendo will do it themselves) makes some kind of adapter with rails for OG joycons on one side and magnetics to connect to the Switch 2 on the other?

Sizing might be a little awkward due to the screen difference, but I recently got the Mobapad M6HD and would love to be able to continue to use them for handheld mode, at least until a Switch 2-specific version is released by them
