Is it, though? If any of the proposed resettings go through, all the vine and moss tiles are probably doomed anyway, as are the green pipes on account of not really fitting into a ruined city of any sort. Things like the Devan statue or the (still diagonal?) waterfalls could be easily transplanted, and most of the rest is simple variations on the basic texture that could be easily redrawn in minutes. Not just in reference to my upscaling in particular, but just in general, if the theme is changed in accordance with most anything on Sean's list, a lot of stuff will have to go and so it's a good time to reexamine what we already have and make sure it's the best stuff to go forward with in the retheming.
