I go the other way, sending pages from Safari to Chrome when I need Flash content, using a TextExpander snippet. It's not a perfect solution for you, but it might help.

Here's the code, which I have tied to "stc " (send to Chrome). [Ha! In typing the snippet shortcut, of course, I sent this very page to Chrome. :-)]

  property theURL : ""
  tell application "Safari"
  	set theURL to URL of current tab of window 1
  end tell
  if appIsRunning("Google Chrome") then
  	tell application "Google Chrome"
  		make new window
  		set URL of active tab of window 0 to theURL
  		activate
  	end tell
  else
  	tell application "Google Chrome"
  		do shell script "open -a \"Google Chrome\""
  		set URL of active tab of window 0 to theURL
  		activate
  	end tell
  end if
  
  on appIsRunning(appName)
  	tell application "System Events" to (name of processes) contains appName
  end appIsRunning
