Yeah if you use a bleach enema for the cleanout! How about the actors in scat movies. You don't hear about them getting sick but I think they make a special effort to keep the sickness and death quiet. If they didn't they would have a hard time getting actors, for those movies, and will have to pay them more. How much would they have to pay you to do a shit play movie?
Seriously, I would do a little rimming, to make her feel good (it feels good when someone does it to me). Personally I don't fined it sexy to see a girl sucking on something with poop on it. Who knows, she might want to tongue kiss next. I have always thought the next thing to do with my dick, after it has been in a woman's ass, it to wash it. But then I an not a fan of licking the rims of public toilets either, that's just me!
None of the women I have done enemas with really wanted to do any kind of scatological things. Actually it was important, to them, that there was no interest in the enema return. My only interest in it is that it makes it into the toilet and that there is no messy cleanup. To me the pleasure of the enema is in having your orifice stimulated, the warmth and pressure of the water and the feeling that somebody else is in charge and they are making me feel good.

P.S. I saw a movie where the girls took enemas, shit in each others mouths, puked in a bowel and the other girl drank it. I was disappointed, nobody pissed on anybody. I was so disappointed I never watched that movie again. (once was plenty for me.)
P.S.2 Proofreading my post against your post, maybe I overreacted a little. The scenario you posed was the girl only mouthing her own feces. I still would not really want to tongue kiss her after that.
