My quick solution to the same problem was to fit DIN41612 as shown...
Is there a way to improve the stray signals generated by the multiple wires used in the mod? I'm just thinking the port coming out the back of the QL is a really cool idea.

It's not ideal but never had any problems with it
It was done initially to allow easy access to an external 3x64K EPROM board (with internal slot TRL disk/memory interface).
Having used a Miracle Hard disk for years beforehand - which uses a 6 inch ribbon cable off the ROM port! - and never had any trouble with that arrangement, I guessed it wasn't any worse...
I did consider a ground screen by lacing some conductive fabric around the wires (like in laptop LCD wiring looms) if I had any problems. But used with Gold card + MHD faultlessly since 1995.
