Have you tried looking into the input method mechanism that 
translates "\'e" into "é"? The info on how do such translations is 
stored somewhere somehow, so it should in principle be possible to 
use it to do the translations you want. I don't know very much 
about quail (I define a few custom input methods in my init files, 
but that's about it), but it looks like the info is stored as an 
alist somewhere of the form ("\\'e" ?é).

Perhaps you've already explored this idea and found it too 
unwieldy, but you didn't mention it anywhere.
