Something a little different here. This is a set of maps made specifically for Skulltag/Zandronum (but would probably work with most doom ports.)
All maps correspond with each other, and entering through certain doors will cause you to end up at certain places throughout maps. Also I'm nowhere near done. Just take a look at my To Do list...

Why not make the entire thing one map? You -CAN- build sectors over sectors now with modern source ports.
