I think it's better to not go for a full kiss, not during the midnight round. This will put both of you on the spot, which is the wrong way to do it, and might even turn him off of you.
You can, however, invite him to a more secluded spot to watch the fireworks in peace, and discuss there, perhaps lean in for a true kiss in private.
A first kiss around people the other person knows is usually a bad idea, unless you were already dating and/or are 100% sure he (or she) will kiss back, which you aren't, so don't try on the spot.
