I installed lxde-core in antiX 8.5 but it failed to start due to xsession-errors related to PCManFM (it opens pcmanfm -d as a default desktop icon/background handler). In sid it works fine. I did it mostly to see what it was made of.
LXDE (full) can be useful for users that want a light desktop environment with a graphic session manager, task manager etc. but maybe it wouldn't add anything for a user used to antiX and its ways.
Just installing openbox and lxpanel, though, on the other hand, may be useful if one likes the simple but comprehensive menu approach or needs a better localization for the menu. I belive one could use lxpanel with IceWM (so no need to intall openbox) but I'm not sure (didn't test) if it could run independently from antiX fully customized IceWM, that is, by launching icewm instead of icewm-session.
