It definitely would not be nearly as successful and I don't think she has the proper vocals AT ALL for that. It'd be interesting though, if she were to release it at the right time in her career and the song had softer vocals it could do semi-well.

I think it would've been more successful. It would've been massive on urban radio for starters. Even though Someone Like You as a song is suitable for that format, it didn't get supported there (probably because Adele is white tbh), so I think if Alicia Keys did it, it would've got sky-high radio airplay, and she's had massive hits with similar-ish songs before.
