Sure, there are plenty of guys doing that. 5.0's running as much as 20psi as daily drivers; I know a guy personally doing 17psi twin turbo'd on an otherwise stock 5.0. The supercharged 3.8L (GM) guys run in the low-teens pretty regularly. My wife's GTP is 12-13psi, and it is only lightly worked over compared to a lot of folks.
