Difficult question.

From a standpoint of 'is it okay to take the session' I'd say yes. If he offers it, it's okay. He has to know how much he can take on and is willing to give, and if he want to then that's okay.

However, even though I intellectually know that, I could never agree to such an offer myself. I'd feel it'd create so many issues down the line for me that I'd not want to deal with that.
