Not just using postfix.  With a milter, it's quite possible.
https://github.com/croessner/vrfydmn does not do exactly what you're
asking for, but it's in the ballpark to give an idea of how to
approach the problem.

I'm curios if it's possible to set up postfix to rewrite the envelop
from address for all email the instance is relaying? I'm doing some
research and want to force the envelop from to be a known value that I
know will pass spf checks.

Is it possible to rewrite the envelop from address for all mail that's being relayed?

I'm curios if it's possible to set up postfix to rewrite the envelop from 
address for all email the instance is relaying? I'm doing some research and 
want to force the envelop from to be a known value that I know will pass spf 
checks.

Thanks in advance.
