I started to port LXDE to TC 2.3 just recently, hope it will be up in a reasonable time.
There are LXDE components which are independent, depend only on GTK2 and can be used as standalone applications in any desktop environment. Such applications like LXTask, LXTerminal, LXRandr, GPicView, PCManFM, ... I will post them as independent extensions in the mean time.
