Not normally possible according to most airline SOPs for the simple reason that, once defuelled, that fuel is classed as 'contaminated' and it is not worth the time, effort or money to do the checks to have it declared 'clean' again. I had a couple of tonnes defuelled from a 757 many years ago in UK and, thanks to some friends in low places' it ran the central heating in the captain's business premises for a couple of years.
