With a little work, you could replicate much of the look of the Sense UI. I'd start with a home app that allows themes. It's easier to find a sense-like theme, but just being able to change the dockbar at the bottom is the big thing as you can typically Google to find one that looks like HTC's. Mix in some Locker Widget (a paid app in the Market) to make your lockscreen look like theirs, along with the Beautiful Widgets, and you'll be there before you know it.
