No harm applying MD except for cost. If you can afford the extra money, I'd just do it. Apply primarily to in-state, low-tier, new, and those schools that have missions that you share/care about. Apply broadly DO as well so you don't have to reapply.
That all said, as others have said your chances really can't be evaluated without an MCAT. Don't take it until you're getting in your target range, preferably above it.
