You could do what I do and go the opposite route. Instead of using guitar stuff, use soprano uke stuff. I have had a baritone ukulele and tenor guitar (in Chicago tuning) for many years and have never looked at a baritone resource. The only drawback is that you aren't playing in the key you think you're playing. For example, most blues books will give instruction for how to play the blues in C. If you follow those instructions faithfully with your baritone, you will be playing the blues...but in G. Or if you do what the book tells you to do in order to play some blues in A, just realize that you're actually playing in E. If nothing else, this is as good excuse as any to learn your circle of fifths so that you can transpose keys.
