You can get away with just mastering the same mix again, most likely. This would be especially true if you employ EBU R128 [0] and other such modern audio engineering practices. I've personally employed automated R128 dynamics matching for the past ten years, in order to output from one stereo PCM source file, a separate dynamically-matched master for each digital distributor's particular LUFS standard. i.e., YouTube's -13 dB LUFS, Tidal & Spotify's -14 dB LUFS, and iTunes' -16dB LUFS.
