What do you think of a horn that would use the linkages from a Bartok valve (like a trigger on a trumpet, but to take the F valve to an E/Eb remotely) to operate a plug in D valve?

I'm not sure I understand.  I would guess that plug-in valves are way more common than Bartok linkages that just move the slide. The main difficulty making a conversion is that the point of a Bartok linkage is to make a LONG linear stroke with a small lever movement, where a valve linkage is there to make a small rotation based off of a smaller lever movement.  Might have some parts to make a lever from, but it might be easier to just start from scratch, depending on the setup.

Cheers,

If it's set up like what Thein uses, that's much more complicated than what would be necessary for a slot-in valve (as Andy pointed out - it's necessary to turn a rather short motion at one end into a long motion at the other). If you already had an instrument with the Bartok setup, you probably could use the Bartok levers, but you might be better served to get a second, simpler linkage (using the same pivot saddles) made for the slot-in.

Yeah, I've seen a few plug in D valves, and the linkage is far more simple than a Bartok Valve.

There's actually some pictures of a horn similar to this in the 'Bass Trombone Appreciation Society' Facebook group that was posted a few days ago. I believe it was a Hagmann valve with a 2nd drop in Eb valve. Unless I'm mistaking your description!
