Just go to the Galleries in T5. I am still confused as to why you want to go back to T3.
NO you can't do that (not since 9/11). Your boarding pass is for T5 so you'll not be able to get to airside on T3.
Sorry, total ignorance to how the airport is laid out for traffic flow. That's why I'm asking questions.
