Slim profile lighting suggestions needed

[Samw]

I am going to get a dual MH system for my 36" long tank. But I don't have a lot of room. What are some of the slimmest profile 36" MH fixtures (175W Mogul or 150W DE) available? Also, what are some of the slimmest profile 175W Mogul reflectors out there in case I want to DIY?

Currently, this Coralife Advanced Aqualight is the slimmest canopy I've seen at 2.75" tall.

Two things that I don't like about it is that it doesn't have electronic ballasts and the included lamps are 20K. I would like something like this but be able to plug in electronic ballasts of my choice and have 10K lamps.

The Finnex fixture is 3 7/8" tall.

As for Mogul reflectors, the slimmest profile reflector I've seen is the Optix II at 4.5" tall.

I've already looked at the mini pendants from PFO, Optix, IceCap, Aquamedic, Cooltouch, etc.

I'm leaning towards the Coralife fixture and replacing its bulbs or a DIY option with a slim reflector. I noticed this slim reflector but know nothing about it so I'm skeptical: http://www.innovativelights.com/pfo-74048bb.html

What else is out there that I have missed? The PFO Optimal and Parallel reflectors are way too tall and way too wide.
