This is fine to do. Marvel comics is to also do this with 'Captain America'.
You have Steve Rogers as Captain America, Danielle Cage as Captain America who has NO connection to Steve Rogers whatsoever, Sam Wilson as Captain America. They are to be a part of a Corp. A team book all linked by the title 'America'.
Since the comicbook character Dani Cage proves that there needs to be no requirement whatsoever that one has to have a connection to Steve Rogers to be Captain America, so to does the comicbook character Monica Capitan Maravilla Rambeau prove that there needs to be no requirement whatsoever that one has to have a connection to Captain Mar-Vell to be Captain Marvel!
