Pokemon Theory - N was Wally's brother?

The look similar don't they? Same hair, same eyes, same skin tone. But the reason why ProtoMario debunked the theory was that their backstories, personalities and desires don't match up. N wants to 'liberate' all the Pokémon, and Wally wants to grow stronger WITH his Pokémon. Also, there wasn't really a reason why Wally would travel to Unova to be adopted by Ghetsis (except he said he wanted to 'start over', but I personally don't think Wally would go and join Team Plasma).
BUT...it is shown at various points that Wally has overprotective family members. They could be trying to make sure Wally is ok because N ran away and they don't want to lose another child. OR...what if N ran away to Unova because his family seemed to favour Wally over him? Or you could mash both the ideas together. I'm only putting what I think here.

I'm leaning towards the second idea I put forwards - N ran away because his family was very overprotective of Wally. This means there is a valid reason why N would allow himself to be taken in by Ghetsis - he needed someone to love him. Also, this may have started N's belief in the cruelty and unfairness of humans.
Also, if Pokemon time is being logical here (it's a big IF, because Pokemon time is never logical), then Wally would be around the same age as N when he appears. This means they could very well be twins.
BUT WHAT IF N IS SECRETLY A CLONE OF ADULT WALLY? Probably not. what exactly would be the purpose of cloning Wally? However I'm not going to rule that out as a possibility yet. A bit of evidence here is that who names there kid 'Natural'? If I was him, I'd go by the name N instead too. The name 'Natural' might just have been added to make it seem like he's a real human, but his actual name could be 'experiment N'.

However, I think it's more likely N is Wally's brother.
Another thing is that Wally's Japanese name (ミツル Mitsuru) comes from the word tsuru (蔓), meaning vine. And if N's name is 'Natural', that seems like a set of names that would suit a pair of twins. Natural and Vine, best friends forever. Well at least until N decides to join Team Plasma.
Overall, I think the best thing I can say about N and Wally's possible connection is that N ran away because he felt like his family favoured Wally and was adopted Ghetsis because he wanted someone to love him.
