Yes, that would work only if you suspended it on both sides from the handles. Do not drill into the lid or hang from the lid. It will overfill with water and just keep pouring out if the cap is not airtight. Just make sure however you suspend it, both sides are equal and I would suggest rope. It doesn't have to be as thick as mine, but it was $5 for a bundle so I got it fairly cheap. Mine is only a 1 gallon waterer too and I have not found it difficult to fill at all. I think that will solve your problem though as long there is no cap modification or drilling. Could be wrong, but just my advice from previous experience with hanging a milk jug with a cut out 5 gallon bucket underneath. If the cap was off or not tight, the waterer poured everything on the ground. Hope this helps
