Not sure why anybody would take on this project, but several modders at the xda-developers forum have gotten Sony Ericsson's Xperia X1 panel interface to work on HTC's Touch HD. From the look of it, X1 installs, launches and works without much of a speed difference, and the panel interface actually seems nicer on the Touch HD's roomier screen. I doubt either company would be happy about this, but if you ever wanted X1's interface rather than TouchFLO on your HTC handset, I guess now there's a way to get it.
