It would be interesting to try a single Honey Gourami and see how it behaves. If it seems happy you may end up with a good balance, if it remains shy and your water parameters are good you might pair it up. The other obvious thing to be thinking about would be to take both shoals up to 6 from 4. While all of this will be playing with overstocking, it seems quite do-able if your maintenance is good. Honeys should be less territorial and picky than Dwarves.
