If you eliminate the skiing lifts, I'd just get a Marker Alpinist tech binding. It's a good binding and can often be found at reasonable prices. Just put it on any ski you want. As for boots, you could use one of the hybrid ones you mentioned or if you wanted lighter there are lots of good options, ...

IMO the best binding for alpine skiing both inbounds and out is the Shift. There is a 2cnd version out now that fixes a few quirks of the first.
