As I understand you're working alone and are somewhat new to this (I don't mean this negatively, so far your releases have been decent, and everyone has to start somewhere). With that in mind, joining the group might serve as a way for both you to gain some extra help and experience, and help the group (and you) to release translations faster and more reliably. Might as well try it and if it doesn't work out you will not have lost anything.
I don't know how relations are between the two of you though, so ultimately you'll have to decide that yourself.

Such requests have been already considered and rejected over the like economy it would create, and also wouldn't help in this case as this is one of the topics people are interested in discussing in this thread. There are plenty of people discussing the chapter itself too though, finding them shouldn't be too hard.
