4x3ft 12ft ceiling 150 hps + 250 hps/mh + 4 36 watt agro-brite T8's. looking for help

I have a 4ft x 3ft closet with a higher than 12 ft ceiling that i was wondering if it would be possible to set the 250 Hps and 150 hps together on a single reflector, I would think on opposite ends of the reflector. I also have 2 T8 fixtures with 4 36 watt agro-brite bulbs full spectrum that i was thinking of placing them vertical. Would it be worth using these? I have 8 ice in veg under the T8's and have the 150 Hps magnetic not being used with a 250 MH/HPS kit on the way(should have just went bigger). My room is covered with Mylar. What i am trying to get at is will the fluorescent light show up to the plant? i was going to use them to get light between the nodes where the canopy shades the rest of the plant. i am open to any serious ideas and would greatly appreciate any input.
I am an indoor noob so please take it easy on me
Thank you in advance
