My impression is that any other kind of pins except those on a real IC
or those on the cheap budget sockets will ruin the holes in a budget
socket, and then the user can't remove your adapter without installing
for example a machined socket between the CIA and the existing budget
socket.

If you have enough energy/time and are willing to do some nasty work
you can solder your PCB on to a cheap socket. Would most likely result
in fumes from the plastic and would need large solder blobs or
something like soldering in pin headers in the holes in that cheap
socket.

P.S. for the A2000, A3000 and A4000 you could put the switch on the
floppy cable instead of in the CIA socket. In theory this could be done
on A1000, A500, A600 and A1200 too, but that would require connections
both to the internal and the external cable.

If the idea is to hook up a Gotek and an internal drive to an A500, 600
or 1200 you could connect the adapter on the data cable (and power
cable) to the drive, and just use one of those spring loaded hook
clamps for the pin on the CIA that selects DF1. It will collide with
any external drive, but it would work without soldering even if the CIA
is soldered direct to the motherboard (were any Amigas shopped that
way?). The Gotek would need to be of some kind which can have it's user
interface passed through the vent holes on the top of the case, or
using the removable cover on the back if it's an A1200.
