What about some sort of tonneau cover. That has zippers or a provision to open the drivers area up. Would work under most roofs probably. Give you way more rain protection for the cockpit. And a splash guard for beside the driver. Those who don't want to have a roof get great weather protection as well for longer trips. Could attach with some sort of pocket over the seat maybe. And if it's raining you just jump out zip it closed and voila its covered lol. My 2 cents anyways your definitely the right guy to share that with. Hope all is well with you and the wifey
Maybe zip around the driver and or passenger and pop the cup holders out during cold weather and heat the cockpit
