If I got the Eastern team, I would go with the Philadelphia Rowdies. The moniker to me fits the city, a noted blue-collar city with people on the wild side of things, a crowd for any event that isn't always agreeable, and is not likely to be told what to do and thus would get Rowdy. Colour scheme would be grey and tan, since those colours don't see a lot of use in the SHL, and the logo would be a scarred guy with two fists up ready to fight.

For the Western team, I'd roll with the resurrection of the Seattle Riot, but if that was a no-go for both city and name, I'd try the Kansas City Pioneers. I believe Missouri was an important location in the various explorations of America so lets go with that. Colours would be black and brown for variety, and the logo would be an explorer-looking guy using a hockey stick as a walking stick, wearing furs, and looking out over the horizon with his hand shading over his eyes.
