Potential problem: there are packages that fail to build.

Short answer: yes, but someone has to not just ask whether it's
possible or tell it ‘should be easy’, and actually implement all this.
Also, have a look at channel-with-substitutes-available.
It's not sufficiently general for your use case though.

Greetings,
Maxime.
