With the right settings, the VM can get very close to the JB tone (not factoring in skill/technique). Joe's sound is mostly Marshall and I have heard him sound like himself on just about any of them. There are clips on youtube of him using DSL100s, JCM900s, 1974x, Superleads, Jubilees, etc. IMO he sounds like himself through each. So you have the Marshall thing covered. I own a Ceriatone HRM 100 and it sounds phenominal. I think it fills out the midrange nicely and adds some sustain/gain/articulation to the overall sound. You would be very close with a Les Paul into Marshall/Dumble Clone rig. BTW, don't sweat the Jubilee thing I don't believe they are the end all be all Marshalls. A LOT of hype and I have heard people prefer much less popular models for their tastes. I personally love the new VMs and own a DSL100...definately not jonesing for a 2555 at the moment.
