Yes. No conflict-of-interest items with LGP. Sorry.
(Not directed at you...)
Having said that, if you're interested in seeing things like that, you need to be honest with yourselves and buy the titles in question, including the X3 title already published. Doesn't matter if you've bought it for Windows in a past life. It's a differing SKU. The industry isn't formed with what anyone calls "common sense". The fact that iD still seems to produce it for Windows with an unofficial "patch" is unusual. Epic seems to have quit that practice and BioWare hasn't done any more than NWN that way- more because of publisher interference than anything else that I can tell. You buy the game for the platform you want to run on it.
