Yes - the odds are the same for any one individual gene no matter how many other genes are involved. You just increase the chances of the Bumblebee Pieds you happen to produce also having the Het Red Axanthic gene.
Also, just to clear things up a bit, you don't have a double recessive gene animal (a "double het"). Het Red Axanthic is one of the unfortunately named incomplete dominant morphs in the hobby.
