Ok, the shelf is done, and worked out perfectly! Pics are below. After it is disassembled, all the parts store easily under the couch, and the microwave fits perfectly in the tub. The bar attached to the wardrobe is flatter than the molding on the top of the wardrobe, so there is no interference when it's folded down for travel.

I put a metal plate on the side of the shelf that is closest to the closet, because the weight of the micro was making the shelf flex on that side; now it stays flat. Next, I'm looking for something to prevent any front-to-back sliding of the micro when closing the door--a "shelf divider" might work for that, or better pads on the bottom of the micro.

All in all we're very happy with this setup, just need a little pad for the front corner of the shelf (DW and I both managed to bump our foreheads there when working on something on the counter). The extra counterspace was wonderful!
