Putting a Mega-ST keyboard on a 520-ST, 1040-ST, etc. is trivial.
ALL that is needed is a cable adapter.  (In fact I've seen a couple of
Atari dealers selling a Mega-ST keyboard as a separate spare-parts kit,
exactly for this kind of use.  The price was around $130).

Of the six wires coming from the Mega keyboard, two are power (+5v), two
are ground, one wire is data from the keyboard, and one is data going
to the keyboard.  Connect those to the appropriate four pins on the ST
motherboard and you're ready to go.

I've done this to one of my systems, but I don't have exact details
about pinouts with me.
