If Matthew Hatton defeats Saul Alvarez, would he become Britain's biggest boxing star even above Haye and Khan?

Matthew Hatton is scheduled to fight Saul Alvarez. Both are relatively inexperience but has already huge fan bases. Matthew Hatton is the brother of Ricky Hatton so he is already well known for being a brother of a former champion who had a very large fan base. David Haye and Amir Khan are pretty good sellers but I think having the Hatton last name would help Matthew and if he defeats Saul Alvarez, i think there will be a lot of noise.
