The 6x spacebar layout sucks so much for putting better key caps on but given how cheap these are and how these one sided pcbs are made and the fact there is no plate I have a theory: you could alter the bottom layout to have winkeyless 7x spacebar layout by:
with a dremel to make the stab holes and switch holes.
an xacto hobby knife to cut and terminate traces.
And some hand wiring and glue to finish the job.
You could also paint the case

I bring this up because it's what I was going to do with my winkey 11900 but I chickened out.
