Since when did everyone on NB complain about everything? It's just a damn emoticon. Seriously, come on. Just because you find it annoying, they should remove it? If that was the case, half of the members would be gone because they are annoying. I'd be gone, probably, because I'm annoying. This is just a STUPID suggestion.
But, knowing what they accept as great suggestions worthy for implantation like censoring ***** (+ rep) while we can still say words like ass, shit, bitch, cunt, might as well say it already: R.I.P. facepalm emoticon. Oh and let's not forget Vision's rule! The rule that states the obvious. How dumb do the members of NB have to be if you have to even state that rule? More so, how dumb do the members have to be to pissed about said rule. It's common freaking sense. However, that's for a whole different topic. Back to stupid requests/suggestions....Your suggestions is what I said it was, just stupid. Although this is just from my experience, I never see an overuse of any emoticon. Maybe you just hang out in the Narutard section. That is where most of the stupid shit goes down.
Note: I can't be infracted for inappropriate language. If they were so inappropriate, they'd be censored, now wouldn't they? Hey, there's a suggestion. Actually censor words worth censoring! Oh, never mind, that's a suggestion that makes sense. Here's one that HAS to get implanted. Censor -rep! That should be your top priority right now. Fits in the quota.
Closing words, actually on topic, as for the replacing the emotion to fit your needs because it's just SO annoying to everyone, apparently everyone just being you and a friend, I don't think it's needed. It's okay. The ones you suggested were really cool, but not needed in my opinion. I do like that part of the suggestion though. I'm not trying to come off as a total jackass to you and If I did I apologize, but some of these suggestions lately are so not needed.
