I too, thought of something similar to this idea - but here is how imagined it would work.

Bot1 is in the quadrant just past the alliance finishline. Bot1 gets the trackball and passes the ball over the dividing wall to Bot2. Bot 1 stays inside of that quadrant. Bot1 would have to be a hurdler bot.

Bot2 is in the opposing alliances' 'homestretch' quadrant, and receives the trackball from Bot 1 and rolls/hurds it under the opposing alliance's overpass (this was my thought before they repealled G36, so you could use a hurdling bot in this case, too) toward Bot3. Bot 2 never crosses the opposing alliance's finishline, and never leaves that quadrant. Bot2 could be any hurder bot.

Bot3 is in the quadrant just past the opposing alliance's finishline and receives the rolled ball from Bot 2. Bot3 passes the trackball over the dividing wall and over the alliance overpass to Bot1. Bot1 doesn't cross any finishline, staying inside of that quadrant. Bot3 would have to be a hurdler bot, but would have to have a long arm that could push the ball not just over the wall, but far enough to cross the overpass as well - at least a 45 inch reach.

A variant on this approach is that instead of passing the balls over the dividing walls (especially if they don't have a bot who can either pass it over the wall or who can cross the overpass from the opposite side) is that the two hurdling robots carry/hurd the ball around to the opposite quadrant 180 degrees around the track, hurdling the trackball when the get to the overpass. And the hurding bot is just past the alliance finish line to make sure the trackball is controlled after the trackball hurdles the alliance overpass. They would stay in that quadrant during the game. The rotation continues until the end game, when the bot on the opposite side continues around and places the trackball on the overpass.
