Conversion kit for full size blazer into single cab?

Hey, this is probably going to sound off the wall but has anyone seen or heard of a conversion kit to enclose the cab, top to bed, with window, gaskets etc to essentially convert a blazer into a single cab pick up?

i have an 87 silverado blazer that i love to death but i want to have the option of cruising it as a single cab. but i dont want the conversion to be permament. pretty much what im looking for is when i unbolt and remove the hard-top, a kit that uses those same bolt-holes to secure a back piece. altogether giving the options of single cab, hard-top, and open-blazer. might also swap out the buckets for a bench seat.

i know some guys who could help fab it for me... but to save the trouble has anyone seen or heard of such a kit?

thanks in advance.

I've never heard of a kit like that but you could fab something by using the back of a pick-up truck cab. I would think that would be fairly heavy though.
