For many bitcoin applications (e.g. HW wallets) you need to set a PIN. The button to set/change the Pin should have a clearly identifiable Icon. I think many people would associate sth. that looks like a NumPad with a PIN.
I do not have a proposa design, but I think sth. like 12 equal size squares in a 4x3 grid might di the trick
Mnenmonic looks similar bit shows the outer grid not the keys.
