Re: --with-source version not honored?

I think your incantation is incorrect: you build foobar@9.0.1, and you replace the source of foobar@9.5.0 only.

For the rest of your question, I think there is actually no way to fix that: when you use ",version", it gets evaluated before you can import the package. Maybe (package-version this-package) would work?
