It's still a little unclear to me. You're in a place where it rains in winter, not snows? And you're slipping on fallen leaves?
The problem with wet leaves, at least in my experience, is that even if you get a tire that grips the leaves, the leaves skid across the road, taking the tire with them. The only solution is to avoid the leaves, or at least avoid turning while on them.
In plain wet weather, I've found Continental Grand-Prix 4-Seasons to be extremely grippy. I run the 28mm ones on my commuter in the three seasons, and the 25mm on my roadies.
And yes, if you can fit cyclocross tires on your bike, you can fit studded snow tires. I run the Nokian Hakkapeliitta W106 on my commuter.
