It looks like the original compression driver probably had some sort of adapter plate to mount on to the horn.
You could get a single Neo tweeter dome module and hot glue it into place.

If you want to use the piezo, mount it in the horn on the front of the box, on a suitable mounting bracket.

What are the 15" 'midranges' you have in the shed?
I'd love to see a picture of them. Do you know anything about their specs?
If they're rugged enough, you could add a bit of mass to them to aid bass.
I would definitely peruse some low cost project 🙂

If you have a 1" soft dome tweeter lying around, you could mount it onto the flange with scraps of timber/plastic.

Organ driver I was gifted a few years ago, and I've already added extra mass with multiple coats of PVA.
I'll pull it out as I need to see if it fits the holes and possibly the screw spacing

Well the organ driver doesn't fit but this one does and the holes also line up
A garage sale find last year for $20-
A bit tinny but that's possible because there's bugger all bass
I put it on the DATS and I am getting some strange and craxzy readings Computer glitch

Re 7.132 which matches my multimetre
Fs 35Hz
Qts 0.98
As it's midrange I don't think the high Qts is a problem in a leaky box and therefore Vas isn't needed
Still need some upper octaves tho

Are you in Perth Moondog? I've got a couple of 15" PA speakers gathering dust I'd be happy to move on for cheap. They were active but one is missing the amp plate.
Well if anyone fancies them they're here 🙂
I don't know if it's been mentioned here yet but didn't one of our members fully damp a pa enclosure like this with putty or butyl for impressive results?

You could get some 3mm aluminium plate and drill the mounting pattern for the box, for what driver you want to use and the middle hole
Honestly unless you already had drivers to go in it, I wouldn't bother, you'll end up spending a lot of time and money for disappointing results
