My thoughts exactly, and it's what I intend to test in the coming weeks. I say 'subset' because the point isn't "here's a full C compiler" it's "here's two wildly different frontends handled by one system". I tried to get started on the backend this Friday, but got frustrated with the restrictions of running on a Mac, I wanted to go down lower and work from the metal for this, so I'm waiting to get access to a device I can start programming an OS on. If I find success, I'll definitely be posting about it. In the meantime though, I am more than open to anyone interested in helping on the backend, it's the biggest gap in my abilities and a new domain for me.
