I very seriously doubt that any of those guys will be traded, until Danny can get a solid pick in return without taking on salary.
Those guys (IIRC) are all on fairly significantly sized expiring contracts...about $20M if you combine Bass, Thornton and Prince. If Danny trades those guys out, he's basically trading away the opportunity to sign a Max-contract free agent.
The only guy left that I can think of would be Avery Bradley, but I'm pretty sure he can't be traded yet and his youth fits in with what Danny seems to be going for - which is that anybody on the team needs to be either:
a) No more than 24 year old
or
b) An expiring contract
Of course there is Wallace, but right now there is no real point in trading him. After this year he will be on his final contact year (and hence he'll become an expiring contact). At this point he becomes an asset, rather than a liability. Danny can either trade him to a team that wants cap space the following year, buy out his contact (with the stretch provision) or simply let him expire themselves.
