>would like to retain the capability to do this work without funding the entirety of the work itself
Oh, then that's easy: just pay them to keep reading work in the field, maybe write a blog, and get into the theoretical side. I'm sure plenty of folks would jump at the opportunity to be on "professional standby" in a field they find fascinating.
Unfortunately that just attracts fakers/scammers, as it’s the perfect role for them. They get to act all high and valuable, but there is no concrete verifiable output expected to be able to tell if they really are able to do what they say or not.
At least until whatever situation you’re hoping to hedge against happens - then you’ll find out you’re being scammed, but far too late.
