From a breeding perspective - if your intention is to use him as a back up to your mojave coral glow (in the event the mojave coral glow doesn't breed well you might have a normal coral glow breed instead) then its not a terrible idea. But honestly, if the mojave coral glow has a bad year I would just use the enchi killer bee as a back up. Bear in mind coral glow prices will only get lower as times passes, so if you like him just for the cheap price tag it's not really worth it.
That being said, if you want to get him just because you like him and don't really care about how useful he will be for your breeding project you should. Nobody can tell you what is the best choice for you, so it really comes down to your intentions and weighing the pros and cons.
