I don't think that would work since the kettle lid is round.
Mine is a loose fit, so I wouldn't worry about it to much. I took a pair of channel locks and bent the rim of the kettle lid out and then sat it on the drum and shaped it with a rubber hammer.
The only problem you can have with a lid is if there are huge gaps that could change your air flow but you do not need an air tight lid on a drum. Some people blame the flair ups on lid air leaks but they are really caused by the change of air flow in the drum when you take the lid off with the intakes open. If you shut the intakes down before you remove the lid you drastically improve your chances of not causing a flair up. But if you leave the lid off too long it will still flair up.
When I fire my drum up and it is smoking really heavy the smoke will roll out under the rid instead of the exhaust, but when it starts burning good and blue it doesn't have a problem.
