I checked in with the ADN team. They do have something that works with VS 2013 Express that they're currently testing. I'll ask them to post a note here when they have something to share (otherwise you can always ping them via the AutoCAD DevBlog, in case).
BTW - I believe the Wizard installer usually checks for a Registry key (or perhaps it's a directory - I forget). You could use RegMon (or ProcMon, these days, I suppose) to see what it's looking for and create the key (or folder) to let the installation proceed. I would think that the template file could then be copied across to the right folder for VS2013 Express, but then it's been a while since I looked at the Wizard/template infrastructure in VS, admittedly.
