A couple of thoughts and a couple of warnings. I have never managed for large crappie. I've generally tried to eliminate them in water holes of less that 25 acres. I'm also often wrong on advice for places where it snows and gets good rainfall.

To get big crappie, I would do the same thing as raising big bluegills. I would encourage the numbers of large bluegills and small bass to eat the smaller crappie and bluegills that will compete with the larger ones for a limited food supply. Eliminate the bigger bass of 15+ inches that will eat the larger BG and crappie.

What do you Yankees think?

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
