I like your method very much. Only I think it is better to promote these tickets via facebook ads than making a fake account. It is too time consuming to add friends, if you add to many your account will go under verification, which in fact means banned. If you go to slow, it takes ages, until you have enough friends, tickets maybe already sold out. Also in this case, you should make a male account, as you are targeting women more than men.
With fb ads you can just target fans of JB and people from Seattle, so you already have target group. Add age range and choose e.g. only woman, so target group is done.
Also I think you can direct link to tickets site, so in 10 minutes everything is done, if you do the account method you need days.
