Semi-OT Best way to carry downhill skis on Subaru Outback

[Wunder]

We're planning a family ski trip this year that is a several hour drive away. Looking for advice on best way to carry four sets (two adult, two child) of downhill skis. Most likely outside the vehicle as would want the rear inside storage for luggage, helmets, etc.

Subaru Outback 2015
Roof rails with integrated crossbars (I've basically never used these)
2" tow hitch (normally with a Kuat bike rack but easily removed for this trip)

Drive from home to Colorado is about 8 hours each way.

What should I be looking at? Bonus points if the chosen solution has some flexibility to also handle cross country skis or summer toys (paddle board/kayak) but not essential.
