First, let me say I have no direct experience in what you are doing - I'm not in the big bore game and don't ever plan to be, and other than Roachcreek I would not be surprised if nobody else posting so far has direct experience in this space either . . . and I'm not about to question what you are doing, as we all get to make our choices on hobbies!
But if you are solidly planning to stay in this space (very high fill levels with very high air usage) then you most likely will end up completely reworking your game for air . . . meaning a whole different compressor set up too. If you stick with Yong Hengs you will probably have several of them as you will be wearing them out and needing backups to backups (and maybe one running while an other cools down). As for the smaller stuff, they likely would just do worse . . .
With that in mind, I'd start rethinking your air source first and then decide what to do about the number and usage of tanks. The first thing that came to mind was a gasoline powered dive compressor, as it would be "portable" to take with you places, assuming you have a truck (or alternately, a generator that powers an electric dive compressor?). Maybe a 6000 psi nitrogen set up would be best? You could fill smaller SCBA tanks off it. Lastly, you could do two 9L tanks in a cascade, and that would give you a good bit more than the 60 shots that two separate tanks would do on their own (maybe 80? - I don't know).
Bottom line, I think Roach is right in that the portables won't cut it, at least speaking directly to your question. But I do think the best answer probably takes a deeper dive into thinking about what you want to do . . .
On the crazy enabling end of things, I know the F-150 HEVs and EV both have onboard power output that can run pretty much anything you want electrically, so one of those and whatever you do with compressors you could put in one of those and easily refill tanks on the fly . . .
