The revamp people are wanting in this thread would require a major overhaul of the game engine. The amount of time and money required to achieve it would be a sizeable amount. To be feasible and profitable is a whole other issue. It is no simple issue to tackle, regardless of how minor changes may seem to be. As such, an entirely new game is more ideal to the pocketbook than working from anything existing. Introducing replacement higher resolution textures alone causes the game incredible lag and often times CTD from overflows.
It sucks, as the game as it is has so much to offer. Some minor tweaks here and there in mechanics, convention, and accessibility overall would be awesome. A project like this would be suicidal financially (anytime relatively soon). It's too bad that Virtrium does not accept donations or offer a public outsourcing camp to the community.
