This looks like it could be a viable solution for something like LXDE-Qt, since Openbox has not shown any hints of budging to move to Wayland any time soon sadly. This project + LXDE-Qt could work out nicely together since this won't really add any more dependencies except for Nuclear. In that case Orbital would just be the WM while LXDE would be the DE.

Additionally, LXDE would probably need to rebrand and have two packages for distros, LDE-X and LDE-W.
