Personally, I'm cool with you playing him from whenever you want to play him. Keith here is actually from episode one of season eight, but I'd been debating updating him. That said, though, the whole cast is from different points in canon, with Pidge and Shiro being the closest, but Shiro is a CRAU with 4 years of another game between canon and here, so none of us match, and that's a-okay! Whatever you're most comfortable with!
