Sounds like you guys are poised to buy the 2nd most useful/multipurpose implement out there (opinion of course!)...
Get a box blade: The FEL can push the bulk of your material forward, then the boxblade follows, capturing what's left without leaving windrows... once you push the snow to where you want it, lift & dump the FEL, back throught the snow pile, then load that bit where you want it...
Wit a 6 ft FEL & 6 foot box I made pretty short work of what we got, and the biggest plus was being able to back up to each entry at work, lower onto the snow, & pull it away... very little shovelling...
Last year was no big year for us, but we had the cleanest parking lot I ever saw, using that combination, the switching out to spread sand after the snow stopped...
The other nice thing about the box blade is you have two plowing directions if you wish... the rear blade portion is great for cleanup and moving snow backwards.
Course I never used a snowblower on the tractor...
