I don't think anything substantial outside of a massive visual overhaul. The biggest problems with TP are much too ingrained into the core design of the game to reasonably expect them to be fixed.
You example of a seemless world won't happen, for example. The maps are devided into separate rooms. They weren't designed to be connected like that, to taping them together like that would very likely require a massive redesign of the map to accomidate this so that walls don't overlap, etc. That is just too much work for something like this. That's more than MM3D had in and of itself.
