I think you will have to do a combination of things to be successful. I don’t think one thing will be a silver bullet.
There are some other options that you may want to consider as far as canker resistant trees. If you like modern cherries (which are generally firmer) I would look at Ebony Pearl and Burgundy Pearl. Both are reported to be resistant to canker.
Another option is to look at Duke cherries. Duke cherries are hybrids of sweet and tart cherries and historically were planted in areas where sweet cherries do poorly. Generally tart cherries have fewer problems with canker and I would expect Duke cherries would fare better with canker as well.
