From my real life experience: your wings are not the main problem - but the
prop. I had 2 flights in where I had to go through light snow for landing
and always the prop. was "iced" (from the spinner to half of the blades
appr. - thats why the prop heating sits exactly there, if you have it ;-) -
when you get out of the airplane and see it you are scared.

If you have to go missed - I have my doubts that you will be able to get all
the power. Now add some little ice on the wings/frame, more time in light
snow, maybe even divert - I am not going to do that again.
