67 Convert from a hard top?

Has anyone made a Convert from a hard top.

I know the rocker would need reinforcement ( or maybe just subframe connectors???)

And the sheet metal / bracing around the back of the back seat and around the roof line where it meets the quarter and deck lid would need fabrication.

I'm %99.99 certain I'm not going to attempt. But was curious.
The rear wheel tubs are different so as to allow the roof mechanism to be stored when in the down postion. Also the trunk torsion bars are unique to a convertible. I would think it can be done but not sure if it would be cost effective .
