I'm sure you could. Especially since Sheps drivetrain is built enough to handle the power his 2.0 puts down(which is more then any 2.4 has ever made). Each have their up's and downs. 2.4 makes more power with less rpms hence saving some trans but is rougher on the drivetrain. 2.0 makes power up top saving some stress to the drivetrain but killing transmissions.

I just think you can accomplish the same as a 2.3/2.4 with a 2.0 and put the money elsewhere.
