If the game has good controller support, then yeah, you can. Using a XIM on PC is basically a middle-ground between controller, you get less precise crosshair movement than native mouse but get aim assist as a trade-off. Native will undoubtedly be better at long range fights on BR modes where there's little to no aim assist, but when it comes to close-mid range fights the jury is very much out as whether controller w/ aim assist has an advantage over native mouse w/ no aim assist. The idea when using a XIM is to get the balance right when it comes to how much aim assist you like to utilise, too much is obviously detrimental while too little, you might as well just go native.
