Marshall amps are a pretty well served territory on the Kemper Profiler. Lots of them available for free ot commercialy. I can't see reason to have custom made profiles done for a fortune. One thing you really should understand ... Profiler rigs aren't tweaked models, they are spot-on profiles of the mic'ed amp/cab. This alone makes it VERY different to anything you can get from modellers. The most complete collection of Marshall amps and cabs profiles can be found at TheAmpFactory (Ultimate Toolkit Pack1). And if that's still not enough, you will find a lot more Marshall Packs in their Amp Packs or at Soundside or on the Rig Exchange. Only thing I can tell you: Be ready to spend a few extra bucks on good profiles. Don't expect the best of the best right out of the Profiler box.
Regarding your request for totally dry clips ... I doubt you would like them cause they have to sit in the mix and thus might sound strange when listened dry. Nobody has the very same guitars or fingers or monitoring that you have. You will have to try on your own. And my personal guess: It's not to hard to get exactly what you're looking for. AC DC's guitar sound isn't complex enough to overburden the Profiler's capabilities.
Cheers,
