I thought this project already went to GB/Necro!
I'm really happy to see this project still alive.
I've currently designing a 60% keyboard that uses the BAE.
If this is going to become a reality, I will definitely go with the ISO stab enter, because up until now, I've been designing around the Tai Hao BAE, which they reference as 6Gv2 Enter.
The weird stabiliser needed for it has been really difficult to source, so all the more for this project to succeed.
