I'm not concerned about a timeline as long as the arms coming back to the Reds are a) close to the majors and b) higher ceiling than Harang or Arroyo or anything else currently in the Reds system (which won't be difficult to trump).
Ok, I'll continue to play along.
Which team out there is likely to (a) have two young, promising, on the verge of being almost-MLB ready arms and (2) be willing to give them up and (III) be willing to trade them for Harrang?
Without a trading partner that meets these requirements then your plan doesn't go very far.
It's definatley a radical plan. I can't imagine the freakout that would likely occur if Harrang was traded for two prospects, no matter how promissing they were.
