You are right about Q1-4, I was in a rush, will fix it tomorrow.
I can test things with a simple current mirror, but I usually resort to a
Wilson if I am not using matched parts. Just habit, perhaps a bad one.

Looks about right, except the PNPs appear upside down. If you're going
with emitter ballast resistors in the mirror, then you probably don't need
transistor matching or the Wilson configuration, and two NPNs per mirror
would suffice. The compliance is pretty much constant since the row and
column nodes hold very close to ground - there's hardly any Early effect.
