What are the options for getting a lower crawl ration out of the stock X (2.72:1) transfer case and a six speed trans?

Atlas does not make the Rubi Crawler for the 6 speed.

Is there a re-gear for this trans case? I know that swapping a Rubi case is an option, but I would like to hear what other 6 speed owners are doing.

 

I am 99% sure there's no lower gearing for your tcase.

Other than regearing your diffs for a lower overall ratio, you're looking at swapping a new tcase.
