Yikes, tough one. I think you are getting a bit scared and trading SJax for less than you ever would if it was week 1. I understand the rationale, as I've considered offering to trade him too. I actually think I'd rather offer Mendy for Tate and hang onto SJax. (If Tate is your target.) I think Mendy will not last much longer as starter.
