looking for 10 inch replacement lid

Father and law gave me his old dutch oven. It is not the camp oven style (no feet or lid to hold coals on top), but I would like to convert it to one by just replacing lid and using rocks for feet when cooking over coals. But dont like the $28.95 price for a replacment lid from lodge. Scoured the internet for used ones or cheaper ones- no luck yet- anyone have any suggestions?
Even thought about flipping exisiting lid over and using underside to hold coals and a pair of channel locks to move it....
Guess I bette ask too if there are any problems with using a regular dutch oven with coals- would not think it would be an issue....
