I'd recommend going clipless and getting walkable shoes.
Combo pedals seem to appeal to the same crowd as the adjustable stems you see on hybrids, meaning non-cyclists, and I don't know any that I've seen that seemed reasonable. The Wellgo platform/clipless pedals that came with my mountain bike certainly kept me from getting into clipless until I got a used pair of atacs, since even with the tension cranked and the release angle maxed, they easily came unclipped, something that never happened with ATACs unless my cleats were very very worn.
I just got used to wearing mtb shoes all the time too, and I'm glad the Lake touring shoes I got are less obnoxious than the full on mtb shoes I used to have. It was a real pain to get my extremely comfortable and stiff Specialized mtb shoes on, but the Lakes are easier to deal with since they were made to be walkable, yet still stiff enough that they're good for pedaling.
