I really wish someone would make a normal-size keyboard with all those extra modifier keys. Yes! The closest I've been able to find is the Razer Anansi, though I'm still not completely satisfied with the layout and I don't like the way its keys feel (YMMV). There are some other gaming keyboards with thumb keys but the Anansi is the only one I remember having found with more than three. It's so frustrating, they figured out that you get extra bandwidth by giving the thumbs more keys, but then they throw that extra bandwidth away by making the keyboard smaller. Oh, right, there's also keyboardio. I've never tried it and it's expensive but it doesn't just have thumb keys, it also has palm keys. And there's ergodox though I didn't like it when I tried it. There are also some generic Japanese keyboards with a narrower space bar and extra bucky bits - I assume you'd have to fiddle with remapping keys for optimal use in English.
