I think the problem would be burn time. These little stoves will burn for 5-7 minutes before needing re-fueling. With multiple stoves You would increase the BTU's but the burn time would still be only a few minutes.
Now, If you're thinking more than one pot -- i.e. a pot on each stove -- one for water one for soup and one for the gourmet entree, Sure, 3 or 4 would work fine. For longer cook times you could even rotate/alternate stoves filling one while the other burns. JUST BE CAREFULL. they look small and innocent but they get really hot -- You ARE dealing with fire here.
I had several at one time. Like a TD, Can't make just one. If interested google will turn up a "bunch" of plans for building.

If it's not broken, you're not trying hard enough.
