yeah would be a good start and should be decently sufficient, and depending on the driver xlg or hlg would only need a 100watter thats turned up a little but saying that if using say the XLG-150-L-AB you could just add 3 more strips for 11 and that would what you could run nominally off that, or say round down to an even 10, as really cost at that point is only what $10-15
Do it 
Over kill unless you need to throw the light at least 2-4 feet before it hits your plants when already in full bloom and even still, more realistic with today’s output i would say 30-40w/sqft but thats all based on efficiency of the light and how far away you are
