Let's rebuild

This is the most reasonable batch of Habs trades I've seen in a long time

Agreed.
But the line combinations leave something to be desired.
I would have
Drouin, Galchenyuk, Scherbak
Hudon, Janmark, Gallagher
Lekhonen, Danault, Byron
Carr, A.Shaw, Deslauriers
L.Shaw.
Also, I think its time to ship out DLR, McCarron, Froese, Schlemko and Alzner (if you can) and make room for up and coming youngsters.

I did the lineup really fast but I wouldn't trade DLR and McCarron just yet even tho both seems like busts. Let's try them this year.

Andrew Shaw should be traded too and McCarron could be call up and play on the fourth line. I just don't know who would want Shaw. We should get a second round pick and level B prospect for him.

You have good draft picks and a lot of Cap space. This will really help with direction of team going forward. I agree with the comments above. I do not see Drouin or Galchenyuk as C`s. I would move both to wings. On RW you have two good young players in Scherbak and Lehkonen, can both handle this over a full season right away next season? maybe in 2 or 3 years but probably not right away. I would move Alnzer Petry and Schlemko is you can. Alzner is being paid for top 4 minutes but plays as a 5 d-man. Schlemko is a 6 D man making $2.1, I would move him and play a younger D or less expensive one. People love Petry for his skating and O output but his D zone coverage is terrible. He is minus 23 thus far.

But I like your moves, draft picks and cap space. Should do well going forward.
