Switching sponsors can be just what we need. I thought thru my changes very carefully (and w spiritual seeking) and had solid reasons ea time.
I would NOT suggest mixing work and program. The program and steps, if done fully, are very intense. You are still newly sober and I am assuming to AA (you don't mention prior time in the program) and you haven't said if or how many steps you have started to work. I'd suggest you think carefully about how deeply you want a co-worker let alone a manager to know the most intimate things you will share in 4 and 5.
I'd consider myself fortunate to have someone at work in the program who indeed has what I want (I had one manager like this for the first year of sobriety and being back to work in a restaurant, it was even better!). Now I work for two people who are amazing mentors and inspirations. These kind of folks are better off as close program friends, for me.
