Reason is actually really sick, you can get some amazing sounds out of it.
My recommendation if you're looking for something to take care of more of the mixing side of things would be to get Reaper (the trial is free and has no restrictions), and some of the Variety of Sound plugins. Bounce your stems out of Reason and mix in Reaper. Problem solved : )
Nothing wrong with rewiring, but if you're not having any problems with the actual MIDI sequencing in Reason I can't really see a reason to do it.
I use logic and love it, great software plus the included instruments and effects are worth the $200 you'll pay for it on their own.
