Eww hard no

To expand on my previous comment. Manson at half off is 100% a first. You could literally turn around at the TDL and get a first back if he doesn’t work out.
Jones isn’t going anywhere, specially as a throw in

And you’ll have to pay to get rid off your two dummies taking up your cap space that’s preventing you to make additional moves.

We'd pay a fifth for Mikheyev if we wanted him, but we don't.
We'd pay a fourth for Dermott if we wanted him, but we don't.
Manson with 50% retention is worth Liljegren and the 2022 second.
Jones is an overpayment that we don't need to add to get the Liljegren/second package because we can just keep Manson and trade him at the deadline (or earlier).
