i am writing plugins for a dotnet 3.5 app, and thus my assembly needs to be CLR2. Is there a way that from inside my CLR2 code that i can load and host dotnet 4 and call dotnet 4 code?

So the sane answer is “You probably can’t call .Net 4.0 directly… but you can interface with it.”
In any of several ways. Including COM, Web Services or something called “Inproc Sxs”:
calling .net 4 from .net 3.5 via self hosted wcf service
Bottom line:
Yes, but you’ll need to wrap your .Net 4.0 functionality in an out-of-process server.
