I think it's certainly a distinct possibility. Talking with the curator of The Experience at Gallifrey in Feb, I got the distinct impression he knows his stuff, has done the research and is happy to use really great replica's if an original prop or costume piece can't be sourced.
Fun fact: That's how I met him - he stopped me in the lobby and wanted to know where I got my 9th Doctor jacket because it was 'more' accurate than what they had.

He then went on to break down the differences between my coat and the screen used jacket down to an impressive level of detail. Like stitching details.
