The stock compressor fits with the AlterKtion? That's awesome.
I'll get some pics of my compressor later. But, if the factory one fits for you, I wouldn't change it.
Bouchellon sells a under hood kit for us hemi guys- $350-$400 for everything under hood minus the compressor (using a hemi compressor). That is a good option for sure.
I might end up piecing one together, and I've found a couple places with a condenser that might be about the right size.
