Hmm? I dunno, it's never bad until you run out of room... and that really sucks when you already have a whole overworld and many interiors done, and you have to do a whole new tileset layout.

I find a general good layout would be to have a tileset for the exterior, and a tileset for the interiors... and addtiledef2 for changing wall tiles(much like palette swapping), and floors and other stuff that would frequently be different. It means less creativity because you can't use outside tiles inside, and vice versa, but you have SO much more room.
