Just a thought here, but why not try Callahan as a left winger? This way you can have Gaborik and Nash on the right side. We all know he's defensively responsible, what's the worst thing that can happen?
It doesn't make any sense, solve any problems or even change anything?
Nash is primarily a LW, Callahan is a RW. If Torts said he wants Nash on the RW, how would:
Callahan - Richards - Nash
make sense? LW on the right, RW on the left. Why?
Also, whether Callahan plays left or right, the problem still remains that four of the top-six are occupied by Richards, Stepan, Gaborik and Nash. That leaves two spots open for Kreider, Hagelin and Callahan. Doesn't matter which side Callahan plays, someone is getting bumped down to the third line.
The notion that Torts has said he wants Nash on the right (which may be taken out of context as it may have been a temporary thing until Gaborik was healthy, which he now is) would suggest that your RWs are Gaborik, Nash, Callahan. Your LWs are Hagelin, Kreider, Pyatt. I'm not at all convinced Nash will play the right though, now that Gaborik is back, but switching Callahan to the left doesn't solve the log jam. If they want Callahan and Nash both in the top-six, Nash will simply play LW. There will still be an odd-man out between Hagelin, Kreider, Callahan.
And none of this matters since the lines change on a shift by shift basis on this team.
