They would have to run it in conjunction with the other stops, and I don't think Breck has the terrain to support that. And especially not at Killington. Would be cool though.
There needs to be more stuff like Cold Rush. Maybe not a part of Dew Tour... but they should exist. Like the Freeskiing World Tour, but with more emphasis on jumps/air style, and a few more pre/built jumps/jibs.
