You you replace it with a solid stopper, then put a carboy cap on top of the stopper and use a zip tie to hold the carboy cap in place. That should do a pretty decent job.
I have some ciders in 1 gallon jugs I do something similar with. Solid stopper that I put a screw cap over top of. They've been sitting for the last four months without any problems.
