Just Buy a tin top

The thing looks okay and it makes the car a lot different.
There was one at the AGM of the MK1 OC, it was a black one on a green car, looked okay.
The problem is really stowing away all the panels if you want the top completeley open.
They are either gonna take up the rear passenger seat or fill the tiny boot as it is.
I think the engineering of a folding metal roof would be a massive undertaking and very costly too.
So a lot of units would have to be sold worldwide at a very low cost, to get folks to part with their cash.
You could do a full top refurb, headliner, interliner, top pad and mohair hood for a lot less and it's easier to put up and down.
I do kind of like it though.
