I'll let this run its course, but only because somebody has made this request a VERY long time ago, and was working on it, but then was banned/kicked out for reasons we will not say.
As far as it being easy, its not. If you think its easy, then you'll have to listen to what peacemak3r says. Its actually quite hard to take 2 routes and combine the two, not to mention the Rockaways portion has been in development hell for the longest. Whether you'll actually see the route who knows, maybe a developer will one day decide to do it.
