To accomplish all of this in one light would be very expensive with the current technology at hand.
If you break this down into smaller systems (multiple flashlights), I think it is totally feasible. Would that be a possibility for your application?
One light with 4 led’s at 300nm, the next light with 4 at 350nm or 400nm… all the way up to 650nm. Pick your step based on available emitters and budget.
Not a lot of throw, but multiple Q8 or Sofirn Q8’s may do the trick on a budget. Others may have a better suggestion for a host (flashlight body) that can be used.
If you need brighter for longer, then you need to add multiples of each wavelength with this stock flashlight. Brightness steps down on high power flashlights so things don’t melt.
So 2 on turbo would be say 10,000lm for an example, but only for a 2 minutes. So you could run 4 on medium and it may get you close to 5,000lm until batteries run out.
Lots of bright people on here so I hope you get some better suggestions too. Good luck!
