First of all, you'll find it difficult to replicate the long runs at Revelstoke (5000 vertical on Snow Rodeo or Devil's Club with black and blue grades into the mid-mountain lodge). I'd say your best bet would be Fernie doing top to bottom at Currie Bowl, Lizard Bowl or Cedar Bowl. Kicking Horse has My Blue Heaven if you want to yo-yo off the top lift, but it is considerably shorter--dropping into Feuz Bowl or Bowl Over and choosing a black run on the lower mountain might give you the same feel. If you like dropping into the North Bowl at Revy then KH, Fernie, and Louise have lots of places for you to play. If you prefer trees and deep snow Fernie, Whitewater, Red Mtn. and Big White are usually pretty good.
Since this is shaping up to be a good snow year (knock on wood), you'll probably find epic conditions at just about any of the Kootenay/Shuswap/Okanogan hills (we had close to a four meter base at BW by the end of the season). How much time do you have? If a week I'd say do a Castle/Fernie/Kicking Horse/Louise circuit. If two weeks I'd go for Castle/Fernie/Whitewater/Red Mtn/Big White/Silver Star/Revy/KH/Louise circuit (possible to cut one or more of the hills out of the loop). There are 15 or 16 good hills available in the Rockies/Columbia/Kootenay/Shuswap region so you have lots of choice. And if you drive the Icefields parkway, the only animals you really have to watch out for are the two herds of mountain sheep, one on either side of the icefields region proper--weather and snowy/slippery roads are the bigger hazards.
