I made lengthy posts in the other thread about why Orianna and Draven could have worked, and even had one of the so called 'elites' agreeing with my points. Were you paying attention at all, or do I have to go dig all that up again?
There is a certain amount of creative freedom that can come with playing a champion. Riot made this very clear when they made the Journal of Justice, in which champions commonly behave in ways you wouldn't expect. It's a little silly if Riot's official lore is more free and flexible than the way you seem to think everyone should play their characters.
And why are you of all people making this thread? I do not view Wukong as a constant troll character. Yes he could be a fun loving sort, but I do not see him as a prankster or someone who meddles in other people's business. He would be focussed on his martial arts to a lesser extent than Master Yi, but still very devoted to the wuju style, (which I think you could probably prioritise more. I rarely see your Wukong training/practicing/talking about martial arts even though he does show skill when provoked). This prankster personality is something you've developed to make your character more easy to identify with and give them a 'niche' beyond what limited catalyst we're given in the lore (which is barely a few small bones to pick). As a result your Wukong has a definate presence on the forums, much more so than he would if you were just playing him straight to lore. There's nothing particularly wrong with adding a twist to certain characters so long as it is within the realm of what they would or could do.
Much of the purpose of the role playing forums in the first place is to entertain. People don't just want to see Champions doing things they know champions are going to do. They want to see the champions getting into new and unexpected situations that challenge their lore personalities. That was like most of the reason why Journal of Justice was even fun, and Corporate Mundo was a sucessful joke. This is why roleplay is such a flexible and enjoyable medium of character exploration and development.
Let's use Kog'maw as an example here (sorry Koggy!)
Kog'Maw has barely any personality in-game due to being a slathering voidling that eats everything he (it) comes across. However due to certain skins and joke lines, it's become common perception to give him a puppydog personality, which is like 80% derived from his joke lines. The current Kog'maw has adopted this stance and as a result comes out as a very likeable character. Now a Kog'maw purist who wants to see the character as a mindless eating machine death engine would argue that's against the spirit of the character, but that wouldn't make for very fun or creative rp's.
Y'all need to use your imagination a bit more. Warwick/Soraka is a fascinating concept on the theme of 'opposites attract', especially when Soraka has ulterior motives. I found that awesome and well played by both of them. The fact that it's Soraka who's getting into Warwick's head and not vice versa is delicious irony.
If we're seriously going to start pointing fingers again and throwing poop, let's make this the last one and get it all out of our (your) system(s).
If you want to be a purist, write a story. It works much better there.
