It's only forever; not long at all...
Well, RE maintenance on a tall tank, that could be solved, or at least partly solved, in several ways. If you had an internal filter, it could be positioned so the flow is greatest nearer the substrate, which means any waste will be blown back into the filter. If you were going to have gravel, you could do a reverse undergravel filter, which stops waste building up onthe substrate plus gives you all the surface area of the gravel as extra filtration.
Personally I think certain cory species would be fine as tankmates. The tank will be at room temp, which isn't actually that cold especially in our modern, centrally heated houses. They aren't going to get eaten, both from a size perspective and that cories are well armoured, not food fish at all. The fish aren't going to bother each other either.
