From a divison balance standpoint, sure 36 makes more sense than 32.
But there is such a thing as hockey saturation/limitations where there aren't enough fans to support all the franchises. There is an inflection point where fans just stop caring as much and the money well runs dry. Where is that point, IDK but the NHL is in THE worst financial position compared to all other sports. Hell, you could make the argument that the WNBA could be gaining ground on them and overtake them in terms of popularity.
