Could I attach a bike basket to the rear?

I fastened a basket to the rear (like a pannier) on my friction drive, opposite the engine. The basket was originally intended to mount to the handlebars of an electric mobility cart. it had a double hook bolted to a flat plate, which had a slot cut in it for adjustment.

I fastened the basket at the bottom to the rear fork, with a short piece of barstock and aluminum angle. Then, mounted a standoff post to the side of the friction drive, and with a double nut, a pair of fender washers, and a nylon-bushing lock nut, allow the friction drive to slip up/down as needed, but still support the basket. (I'm using the slotted plate to allow up/down freedom to the friction drive. The basket stays fixed at the same height, but, is supported by the friction drive frame at the top.

I'll post a pic or two soon.

The picture really helps visualize what you're talking about. Now anyone put one on the other side?
