Actually, the default xetex and xelatex formats assign \catcode 11 to  
everything that's classified as a "letter" in Unicode, so you  
shouldn't need to do anything special for this to work.

Alternatively, you could make ŋ an active character, and then you  
wouldn't even need to prefix it with backslash or leave a space after:

   \catcode`\ŋ=\active
   \def ŋ{\your\definition\for\eng\goes\here}
