For what purpose? If participation dwindles they may be forced to do it someday out of a lack of viable bodies to field a team, but I don't think there are "too many". It just feels like a lot of hoops to jump through to even start your 6 year clock. Even if a player "speeds through" the minors (i.e. 2-3 years from draft to majors), you're talking about a player waiting 8 or 9 years before free agency. No other major sport has such a long wait. Also, how many of the players at AFL/Short-A are viable prospects? How many warm bodies are floating in the minors? No other sport (outside of hockey, which has its own convoluted system of Junior/Minor league teams) has so many tiers of prospects below the big leagues Consolidating dominican summer leagues, short season ball and low A into one isn't going to make the journey to the big leagues any shorter. Guys don't take that long to break into the majors because it is mandatory to play at each level.
