MH retrofit kit for PC fixture

[sfarid123]

Hi guys,

I currently have 48 inch 4x65 Watt Current USA PowerCompact Dual Satellite Fixture.
Is it possible to retrofit a MH for my fixture by removing 2 of my flourecent lights ? Id' like to have a setup of a MH and 2 PC actinics. Also would the fixture fan be enough for cooling?

If so, what kits are out there?

Thanks,
shawn
