Actually, I wonder if a simple 34-way Y splitter between the motherboard
socket and the existing drive, and a 4-way one for the power supply wouldn't
do what you need. The user would just need to unplug his existing 5.25"
drive, plug in the Y adaptors, and plug the 3.5" drive into one end of the
Y, and the 5.25" drive into the other.
Is this what you envisaged? Care would need to be taken regarding
terminations (though terminators on 3.5" drives are non-removable anyway)
and drive selects.

Thanks for this, I am aware of the disc drive power splitters but the
idea was "Here is your new 3.5" drive. All you do is plug component X
into existing component Y and you have a 3.5"/5.25" double drive.." ie. no
need
for the end user to dismantle anything from their existing system, no
soldering,
unscrewing, etc. but I don't think this can be done.
Best wishes,
Ian

Have you read http://mdfs.net/Docs/Comp/BBC/Disk ?

Standard disk drive power 'Y' connector - a 5.25" socket on one
end of a short length of 4-way wire, connected to a 5.25" plug and
a 3.5" plug at the other end:
-----------5.25" plug
5.25" socket/
\-----------3.5" plug
About 2 or three pounds from your local PC box-shifter.
