Between the pad height and the solder mask height, I think there's still a slight difference there, though it's probably small enough the solder won't have issues bridging. Like <1thou or such

My feeling is it's probably a bad idea, but it'd probably work. There'd be a height difference possibly making it harder to solder, but that'd be small. The other issue is the loose pins could easily be damaged and pushed into enough other.

Been kind of on an odd kick of making @npub14su…09w8 compatible modules since @npub1y7j…hczt convinced me of a project with it. Spent last night routing a quad UART (16C554) board with full modem control lines for each. Was quite tight to fit in the ~50x100mm board profile.
Now just need to wait a few weeks for it to be made an delivered, that's the hardest part.

Seems also like plenty of space on the front too for power planes too if 2 layer was desired. Don't forget some decoupling caps too though, especially when running these at high speeds

if your goal is that 20MHz 65C816 keep in mind the 3-8 decoder is adding some 5ns or so to the delay path. But looking good. Personally I'd go with less ICs on a module in exchange for multiple modules. Makes it cheaper to get a bulk batch done for the same capacity
