I don't think it could yet. Mexico's national team would have to make some huge strides in IIHF play just to get the country's attention. They're still in Division IIB and have never finished higher than 32nd in IIHF standings. They did win the Pan American Games gold medal in 2017, but it'd take a Miracle on Ice situation to happen before hockey would make a dent on soccer in the national consciousness. Right now the Liga Mexicana Élite (their top-level league) only has four teams (their logos and team names are fantastic) and they're still trying to figure out how to get a youth hockey pipeline going.
