Any chance of through checking bags from BA to VS?

Hi,
Answer, I guess is probably no. I'm flying (VP) NCL -LHR via BA and then LHR-IAD (VS) same day. I will only have one trolley bag + hand baggage but am feeling lazy and don't want to spend the time waiting in the baggage hall at T5 (last time on a very quiet weekend, I waited about 30 mins for one bag).
