If it's a low stakes fishfest you can consider donk betting 2 pair or better hands on the flop assuming the board texture isn't too draw heavy (donk betting a draw heavy board with top pair or 2 pair would be suicidal), and include more speculative hands in your overlimping range. The reason for this is if its a passive table everyone may check and get to see a free turn card.
I find it interesting that you say donk betting in this situation would be suicidal. I would have thought that's quite a good spot to donk bet. Top pair or two pair is a decent hand, and on a draw heavy board I would want to make my opponent pay to see another card. If I check here then it gives them an opportunity to see a free card to complete their draw?
And if they call and the draw doesn't complete, then you can keep betting, and if it does complete then you can slow down.
