AP with WE Service Implementation?

Has anyone implemented AP with WE Service into their CSP classes/have any advice for which code.org lessons to tweak/replace with service lessons? The program is pretty cool because it integrates the stuff we do with real world applications, but it is unclear to me how to cover all the normal material AND the service project (students need to spend a min of 20 hours on it??). One of their guides has like 8-10 lessons in it, and the schedule is already super tight as it is, lol. Thanks!
