I don't think anyone can answer that for you. How much experience do you have? What's the toughest project you've completed? A lot of guys have built Staggerwings, so it's possible for some people, but your skills and patience are the determining factors here.
It will be a long project and if you don't like building then it's probably not something you should take on. If you like tedious stick fitting and detail work, then it's a great project. Unfortunately, I think Staggerwings are some of the ugliest planes ever designed so it's not something I would build, but again, your opinion is the one that counts here.
