Hell, they could take a picture of the transformed Hinata and blackmail Kakashi without actually having gotten a picture of him. Likely would've led to a rather funny episode if left in the hands of Naruto.

Still grateful that they gave us an answer to what's under there, though.

If I were to guess, I'd say that they wanted the satisfaction of figuring out for themselves by seeing what was under Kakashi's mask, a sense of accomplishment and all that.

Having Hinata take a look and either draw it or transform into Kakashi would have been very anti-climactic, especially given the numerous prior attempts they've made to unmask him. It's as much about the effort as well as solving the mystery of what's under the mask.
