I personally think it's a great idea, but you're gonna get a lot of pushback from petrol purists, especially if you do it on something rare. Maybe don't do it on a Ferrari GT250 for example because you will get murdered. I like to emphasize that this isn't a threat from me, it's a warning to be careful. I'd actually love to see the reactions. From a safe distance of course.

I mean, why not? It's a great way to keep something old and loved going in a more useful and environmentally friendly way. Go for it.
