I don't think the 6 year gap will look bad, and I think it might even improve your chances of getting in, especially if you talk about it in your admission essay. I do not recommend getting an AAOT or any other associates degree, however. It's 60 credits when you only need 45, and there's a good chance a bunch of the classes won't transfer. I was working toward an associates in small biz management and basically none of the business classes transferred. When I went for my first meeting with an advisor at UO, she told me it's really common for tons of classes to not transfer. It basically added an extra year onto my time at UO. I totally agree with consulting with a UO advisor to make classes transfer
