That would be ideal.  Just remember that the 18V winding will be rated 
for half the current that a 9V winding would have been, and that still 
applies even if you only use half the winding.  In this case I'd 
definitely follow Tony's advice and get a transformer rated for 50VA 
(18V at 2*1.4A) or more.
