On the participation side the obvious alternative for the US is to grow indoor cricket. Run social competitions in sports centers during the baseball offseason and promote it to baseball players as offseason training as there is a skills crossover. Indoor cricket requires less players, has shorter games and doesn't need huge fields (fits on a basketball court) or specialised pitch preparation.
