I think you're on a better track following what
@MedicinalMyA$$ suggested above very nicely. I have no experience using the bridgelux strips but purchased some a while back, just haven't got around to using/building yet.
Not sure what your budget is or where you are located but you could maybe do some kind of bridgelux eb gen3 two foot strip build. Arrow has a pretty good deal on some 320 watt 24v drivers right now that
@ilovereggae pointed out in a different thread. You could even do two different spectrums, 90cri being an option too, on different drivers to have a little control over everything.
https://www.arrow.com/en/products/lne-24v320waaa/delta-electronics -- two drivers for $95

So would come out to roughly $325, have to add taxes and shipping on for more exact number. This would give you a pretty cool set up in my opinion. Wiring seems like it could get messy doing 40 strips in parallel but my wire management skills are non existent, so maybe you could work through it better. Also, with those drives being 24v, you won't be able to draw the full 320 watts the driver is capable of. The eb gen3 two footers only use roughly 20volts, so the driver will only put out +/- 270 watts total (20v x 13.4 amps). The positive side to those drivers, other than being pretty cheap, is that they would put the strips just under their nominal current of 700ma each (13.4 amps / 20 strips = .670ma per strip). That could maybe help out keeping the costs of framing/building down since the strips really wouldn't require any/much heatsinking. This will still be quite short of covering that whole area at only around 540 watts, you could double everything and probably come pretty close to covering the whole area or wait for another day after funds become more available.
Sorry I rambled on, hopefully it just gives you another option to weigh out. I by no means am an expert on anything, so please don't take anything I said above as a concrete build. Someone will hopefully correct anything that may be incorrect. Just my two cents on a nice pairing without breaking the bank. Good luck however you go though and I am sorry again if this is a jumbled mess.
edit: You could also just use some of these,
https://www.digikey.com/en/products/detail/bridgelux/BXEB-TL-2750G-3000-A-13/7899252 just an older generation of diodes, but essentially the same concept I tried to describe above, just all on one strip already. They actually would fit the 24v drivers better as well.
