How about a fixture full of 20-70w bulbs? 600-1000, watts all spread over a nice even scrog canopy. Lower ceilings in mind...
I've been thinking about this as well and there are bunch of guys on here who are getting really good results with mini CMHs.
On the German sub forum... growing pure sativas under 70W&35W CMHs. Was quite impressive.
I turned towards LEDs as the heat and breaking threat of the CMHs was a concern for me as I'm frequently leaving my plants alone for 2weeks+
Those guys however never seemed to have problems.
