The data files we did are for RAZOR COAST - not the Lost Lands nor anything else FGG has created. We certainly aren't recreating everything from FGG. The files from us are independent of everything else that FGG has done, so I'm not aware of any reason why they can't be used together. There may be a few things duplicated between the two sets of data files (I honestly don't know), but they are independent of each other, so they should co-exist - so you to choose which version you want of something that happens to be duplicated. As such, I believe your concerns are non-applicable to the actual situation.
