I would advise you speak with an ALO but...they're not going to be able to tell you anything other than "from my experience, you would fit in this category of my history..."
I've seen candidates that were stellar...that didn't get in. I've seen candidates that had HORRIFYING fresh/soph years...and turned around in a huge way...and it didn't help....and it did help; it really depended upon the candidate, the alignment of the stars, etc.
That's my "cute" way of saying this: do NOT let anyone tell you that you CAN or CAN NOT achieve your goals! ONLY YOU can make that call. If this is something you desire, then go after it with everything you have! If it's not, then press ahead with whatever fuels your passion.
Others can assist, suggest, mentor...but only you can do the work.
