MH upgrade for PC fixture

[Kris&Dad]

I am currently running a Coralife Aqualight Deluxe (4x65w, 48"L x 7"w x 4"h) on my 55gal (48"L X 13"w x 20.5"h). I would like to increase my lighting with MH, if possible. Is there a way I can fit the MHs (and extra fans, if needed) into the coralife fixture. Or are there smaller MH pendants that will fit behind the current fixture? Or other options?????
Also, it is getting close to the time to replace my bulbs (2-65watt 10,000K and 2-65watt Actinic). I would like to have a bit bluer hue to my water. Is there a better combination of bulbs that will do accomplish this while still supporting my reef inhabitants? (Deresa Clam, cup pagoda, bubble coral, devil's hand, toadstool, asst zoos and mushrooms, candy cane and frog spawn corals)

Thanks

It does not look like there is enough room to fit MH in your current fixture. You could tear it all apart and build a custom hood to acomidate the new lights. I have been running PC with VHO and have thought about MH. The only way I can figure this out ( with out the top of my tank looking like my four yr old put it together) was to design and build a complete hood. All lights attached to the top of the hood that is hinged so i can easily access the tank. my 2 cents anyway
