Tempting approach, but I think it would fail miserably. Excluding with wildcards would proably excluded everything. But instead, you want to exclude only the directories that are actually in the other backup jobs. So, you will want to go for explicit excludes.
I think you can get away with some copy-pasting from the explicit includes to explicit excludes.
Manual distribution is error prone. I hope you will do some testintg and restoring.
