An idea just came to mind... The standard KPBS 1.25m adapter mated to the bottom node on an MKS multi-hub, while not perfect, is close enough for bases that just sit directly on the ground. So what if, instead of adapters, I created longer KPBS-style legs to match the height of a Duna module when it's deployed and then maybe something akin to the Tundra cradle that snaps to the bottom of KPBS modules to hoist them up to Duna-height as well? I might still want to create an adapter or two (the KPBS garage comes to mind) but it seems like simply having longer legs would eliminate a lot of the need to have multiple adapter combos.
