Context:
At work, I code primarily with Java.

I'm a big believer in the mantra, "if it ain't broke, don't fix it", but I find myself conflicted with that when I can see how much of an improvement it would be to use a different language for some of the simple pieces in our integration.

Question:
When should one start considering other languages for your team? And if you choose other options, how do you do it in such a way where you don't end up building a chimera of an integration?
