Sounds like a worthwhile item to have, especially not stringing wires all over the bike. I presume the C&V market for retro lighting might be limited?

And most of the "Chrome", and "retro" lighting I've seen is either generator-driven or powered by expendable batteries . I'd think USB-rechargeable would be better. And lights that do not require brazed on fittings would be a plus?

While wishing upon a star, a retro-themed bike computer would help, and not look so out of place on C&V bikes, unlike the black plastic ones.
