Having a 20X 50ft conrete slab removed on Tues, tree soil question

The slab is located on the east side of our house.

Removing this slab and the associated concrete blocks underneath it will leave about a 2ft depth throughout.

Can I fill 1 ft of it with regular dirt and the other 1 ft with topsoil? I don't want to imagine the cost of filling a 20X50 by 2ft with only topsoil. I'm trying to lessen the cost by using dirt for half of it, but I want to make sure that 12 inches is enough for trees and shrubs.

Thanks.
