I would be into it.
edit:
That said, I don't think it would affect the underlying issue - romance is companion content, and it touches more than just "romance". To remove romance from certain companion, would require alternative content that would cover relevant story archs, without aiming for a romantic relationship. And example of how it can get weird is Cyberpunk - a game where romanceable NPCs aren't player sexual, and will romance V only if they are the right gender. Works from a different side than what OP suggest, but it's pretty much the same principle. The issue is, that for the most part whenever you romance someone or not, it is the same content, it just doesn't end in a sex scene. Personally, I still found those weird, because they play out like romantic encounters - you just never get an option to seal the deal.
Making companions fully romancable and non-romancable would more or less require to create different content for each version. Which is not unthinkable - we do get only handful of companions.
Eh, romances continue being a bane of RPGs companion. If I want to play a bad dating sim, I will just buy one on steam.
