The solution that I am using for this is to rewire reason into another DAW (Reaper). Wire the guitar input from Reason into a Track inside reaper (there are youtube videos that show you how, it is very simple) and than use the POD farm VST to get any licensed amp/sound.
You can still do all your work inside reason. When you are happy, make a guitar stem from reaper and bring it into reason, right before the final mix (again this is very simple).
An added benefit is that you can use Markers inside reaper to get to any place in the song quickly with one key stroke, makes navigating to a "solo" or "Verse" a piece of cake.
