Hello there~!
I should start off by saying your plot idea doesn't sound bad at all. I did something -somewhat- similar and ended up finding a brother for my character.
Admittedly, if I recall correctly, I PMed the player (Duplicitous Rex) after reading his directory page. It just so happened he wanted to play a Hellsguard Roegadyn also, and he joined not long after I did, so we set things up. The vague background I had worked well with his character and I can at least say that Klarimel, Siobhain's brother, has had a rather large impact on how she perceives people.
I didn't have a great idea for a future plot, however, so there wasn't the concern about whether or not our future goals would work out, more our histories. I think it maaay have helped him to flesh out a bit of his background as well.
If anything, I'd say that the prior knowledge that the person playing your character's brother might be a murderer or at least is being considered one might make some people hesitant about the idea. Can't say for sure though. I know what we did worked out for us, but then, I was extremely fortuitous to find him before ARR launched and so that might have factored in some of his willingness to connect our histories.
I know of two Miqo'te who are also related so they might have suggestions on how they found siblings ICly as well.
I think the idea is good, and as you said, it's intentionally a bit vague, but it might help you out to start with trying to find a sibling and knowing how you want -your- character to be (predominant class, race, morals, personality, etc.) and save what you might like their plot to be until after you find someone who might be open to the idea.
It's just a suggestion.
