My gut instinct is that this wouldn't be particularly hard to build. I'm not aware of any extensions that do that, but I wouldn't be surprised to see some extensions start to fill in mobile gaps once it's easier to install them, so you might get your wish. I'm certainly going to be playing around building mobile extensions just for fun; absolutely zero promises but if I'm running out of other things to build or if it turns out that this is easy to implement in a single weekend, I wouldn't be opposed to building a quick addon for this and Open Sourcing it -- that's assuming I'm not underestimating how annoying it would be to rewrite URLs in the page or something.
