No, sorry, the portal won't remain open if you use it - what if you drop a pyramid and then reenter this way? I'd save first though.

Sorry, just tested it - doesn't work - the teleporter pyramids don't work at this moment. Tried to run out of the room to place them outside = Mardaneus comes and talks to you (cut scene) - if you return into that room then all monsters are already dead, so no XP for killing them.
