Magnum swap with using newer a/c components
Not without custom adapters, there's a guy on here, who used the magnum suit-case badass71 I believe, was a nice build for ideas..

I will be doing this eventually, because I'm in the same boat, but I plan on retro fitting a newer evaporator into the stock suit-case so I can run the quick disconnect lines the Magnums come with.. We'll see how that works out..
