Live and Jersey Raptor

Hi I had a few questions regarding jerseys with jersey raptor. For some jerseys I dont d-load them I just save them as a .bmp and replace it with a jersey that has numbers as close to the jersey as possible. I was wondering if somehow I can use the numbers let's say for the Timberwolves away jersey numbers I can use that for a fictional alternate jersey so it could match with the wordmark and etc. So if u know what I'm saying I'd like to know how to do this. Thanks.
