Thanks, and also thanks at all others above for commenting. Helped a lot :)
That's also what I've heard (SJ-200 vs J-200 names); it was mainly marketing related, but I could be wrong. I read or saw in some videos that Gibson used SJ in some years and J in others, but the guitars (size and build) are apparently the same. Indeed, please correct me if I'm wrong.
Yeah, a Hummingbird and an SJ-200; I thought about that, but it's a stretch to pull that off.
Where would you come about a good condition used SJ-200? I've checked eBay, loads of listings from Japan. Is that something?
