BA192 always comes into Terminal 5, they don't chop and change terminals. If you are on a BA flight number greater than 1000 (e.g. BA1589) you're actually on an AA service.
Your other option, luggage wise, is the same left luggage provider has an office at Paddington station so you can leave stuff there and collect on the way back to T5 without too much hassle, assuming you use either the Heathrow Express or TfL Rail services.
