How can I layout these regulators to minimize board size and EMI?

I have three switching regulators. A 12V, 5V(green box), and 48V(purple box). The plan is to supply both regulators through -/+12vout pours. If I am trying to minimize board size while also minimizing EMI, what is the best strategy for laying out these regulators? If I pack the components as much as I can, what will the consequences be? A professional perspective on how power should be routed to the green and purple regulators would be highly appreciated. Lastly, any criticism of current design is extremely valuable to me.
