it would be neat. But i think the creators are going to stick to canon for now.
The thing is, IF it is to be believed, they ARE actually going to stick him into the next season, I saw the article posted on Google+ ages ago (and now can't find it) but it mentioned that Mycroft is wanting to add Sherrinford into the show in the next season and thus making that Sherlock line "I am not given to outbursts of brotherly compassion. You know what happened to the other one” wasn't just a random throw away line but one foreshadowing that it could possibly be true.
So what you are saying is that the "older brother" is not canon? And they might do a backstory for him in season four.
The 'older brother' has never been canon, Sherrinford was the name Sherlock was GOING to be named but Doyle decided on Sherlock instead.
And yep, they are, if the article I read is true. season 4 will probably have Sherrinford in it.
