I think the terms you’re looking for are “choc spacing” and “MX spacing”. Choc spacing is what the Piantor uses where the space for each key is 18 x 17 millimeters. MX spacing is 19 x 19 millimeters.
If you want to keep using low-profile switches, there are a handful of boards that either choc or MX switches, and any of those will always use MX spacing. That said, I don’t think there are a lot of pre-built options in this space.
Maybe check out Klor. I think that one is offered as a pre-built by beekeeb and it uses MX switches. It’s got the more aggressive pinky stagger, but it also has some splay which may or may not be your thing. I just finished building one using tecsee “medium” switches and MTNU keycaps, do it’s lower profile, but still not as low as choc.
I’m curious what you think about that little joystick; do you find yourself using it much?
