It would still be a lot easier. Besides, if this is true, then Harry’s cover story to McGonagall about being in Mary’s room is blown. Especially with the heightened security, the Aurors would have noticed her patronus. Unless communication between McGonagall and Dumbledore + Aurors is especially poor, this would tell them that Harry is in there.
Normal patroni can be identified, tracked, and presumably dispelled, so there’s not much of a reduction in risk.

Edit: Sorry, fixed.
Spelling.
Edit: Downvoters: What? There are 4 misspellings in that paragraph (plus nonstandard capitalization). It hurts.
