If you wanted to do the mod, it could be done two ways:

1) changing Caelians to size 2. This would also make their formations tighter, and thus they'd be easier to kill via AoE spells. It would be out of line with similar creatures, as winged humanoids are considered one category larger than similar-sized humanoids without wings.

2) giving Caelians supplybonus 1, giving one supply for every two they eat.
