I manged to get hold of a mouse adapter for the CDTV so have been able to test this relocator a bit further...
I built a CDTV specific TF536 with the right angled IDE header and the relocator permanently soldered to the accelerator (Male pin headers only, no female pin sockets).
The idea behind this was that with the right angle IDE header installed the cable exit from the header points vertically so unfortunately takes away some precious additional headroom. The combination of the IDE header and cable was essentially the same height as the socketed (ceramic) CPU so in this case I could retain the socketed CPU while still having the CDTV lid close.
The TF536 with the relocator installed and the lid closed boots and runs game + memory tests on 3.1 ROMs so far without issue, so I think it's good to go from a physical fit and electrical point of view. Obviously the CD drive is not currently functional with this setup due to the autoconfig conflict with the accelerator.
The closed lid seems fine - provided you don't put anything ridiculous on top of your CDTV like a Nintendo Entertainment System or a 1084S!
One disadvantage of the lack of female pin header sockets between the TF536 and relocator means that the 030 socket pins and the relocator DIP64 pins come very close together, this can be mitigated by clipping the underside of both during install.
Here are some photos for your perusal:

Home made "Go0se brand" 030 socket installed, might as well throw in a few more points of failure to this test!

No "Bulge" with the lid closed. There is some margin for vertical adjustment when screwing the case lid back on. The fit seems snug but the IDE does not seem to be pressing on the underside of the lid.
