Wow. Count me in! I love HM.
As for the town situation, I think that it'd be best to use either the HM64 or the Mineral Town map. Those are probably the best suited for what we're going to be doing. The AWL/DS town is just too.. egh. And we may not even need the whole town; we might as well just make up our own town. With all the fabulous graphic artists here, I doubt it'd be much trouble to just whip something up.
