Ooo, another thought:
If you're better than me with a soldering iron (wouldn't be hard) how about this?
There must be room for the keyboard adapter's socket (there's room for the Lyra).
How about desoldering the socket from the pcb, solder in some extension pins, then reattach to pcb..?
A much neater approach that would make room by raising the PCB above the Indivision...
...a bit fiddly I suspect, but would look fine post butchery.
