Now that you'll have the blower I would think that will be your primary weapon against the big snow, maybe scale back cost/size on the blade a little.
560#s wow that's heavy! I don't think you want to use your loader as a dozer platform, then you would need a HD frame mount, JMO.
How wide is the blower, maybe a 6-6.5 plow is all you need now, like you said that blower adds a curve ball to your needs now.
