So question: If drinking water is RO water, is it possible to just buy a bunch of 1-gallon jugs of water and do it that way if I wanted to?
Yep
with the exception chlorine and chloramine which need to be taken care of.
1) I hope you're getting a tank larger then 5g.
2) IMHO and IME a tank properly balanced out and stabilized with fast growing macro algaes can use any potable water. Most expecially for a fo tank. and for most soft corals as well. sps and other hard corals you could have problems though.
What I do is just "age" the tank fishless for a week with the macros growing. then just replace the water that evaporates with untreated tap water. that way the macros condition and filter the water making the system balanced and much more stable and forgiving.
But that's just me and my .02
