Question regarding 2-mathematics: Can you stackify a 2-functor without prestackifying it first?
Thank you very much (can't yet upvote, but will when i can :) ). I will have a look at that paper, but I think this should answer my question.

EDIT: Also since we are assuming that the associated stack already exists, would that difficulty still exists?

What do you mean by foundations? Do you mean the site structure? If so, could we assume that for very good sites, this proposition would hold?

Hmm.. Thank you very much. So there is at least a 'high chance' that it works in 'good situations'. That is indeed good to know. Anyways, if anyone has an actual proof, it would be much appreciated if you could give a citation. Thanks again.

Thanks for the answer. But then, what about doing the descant data twice, or probably 3 times, i.e. defined $A''(U):=2$-$lim_{\mathfrak{U}}(Des(\mathfrak{U},A'))$ and then again $A'''$. Would that work?
