People have bred coastal jaguars to pretty much every other Morelia spilota subspecies/local out there in the US. The IJ jag would most likely be 50% IJ and 50% coastal. Personally I prefer pure coastal jags, but there are jungle jags and I believe diamond jags out there as well. I can't really give you a price to expect as I haven't kept track of the market for carpets much this year.
