I'm with you. Doing a turbo application is inane unless you're just looking to get into a magazine. Doing it right requires A LOT of work, a LOT of time needed to get it right, and there's a still appreciable level of danger to the motor. I could see it if you're building a non street legal car for the 1/4 mile (and if you were, why not get a crate motor??)
The 6.1L seems to respond so well to non forced induction upgrades that a supercharger sort of isn't the no brainer that it is for other motors. I'm pretty sure the Charger guys are getting ~500HP to the wheels with the mods you listed. That's more than enough for me.
