This is the visual of the plaza near the baseball stadium. You can clearly see there will be no parking on the third base side of the stadium, only walkways. It was a in a gathering I was told by someone in the program that the batting cage area was being looked at for the clubhouse and coaches offices. That will give ready access to parking as you mentioned and would be a nice new facade fronting Reinhardt. My question would be would we then move the home dugout to the first base side.
My idea for the facility would be a three story facility with a roof deck for guests (or rental) and indoor hitting/pitching/locker room on the ground level, lounge/meeting/study areas on the second floor, and coaches offices and meeting rooms on the third floor. If the roof deck isn't an option, I'd go with balconies on the east (field) side to give seating for coaches/players/guests or even the north and east sides. Sorry, just imagineering.
