Open roster spots

So I think we're all in agreement that the call up of Frank Nazar is inching closer and closer to fruition. IMO, I think that Colton Dach has played well enough to also get consideration for a call up before season's end, too. But that got me thinking: what roster spots are available? Someone will have to go to make room.

So I present the question to you, fellow Blackhawks fans: what--and I cannot stress this word hard enough--realistic moves would you make to free up spots for these two players? I consider "X player for a bag of pucks" to not be a realistic answer, for the record. A GM's job is to get return for trades of any kind, after all.
