Both of trades, IMO, are a loss for you simply b/c it is not a guarantee that Rose is playing this season. Even if he does play, his abilities after surgery are unpredictable and, depending on if/when Rose returns, he may only give you roughly a month's worth of production.
Also, as you noted, Lawson is hot right now and is a legit PG anyways.
In regards to the second trade, even if Rose was healthy, you would lose on the trade simply b/c Conley, Lawson, Batum produce substantially more than Gallinari, Hill, and Rose. Gallinari is a streaky shooter with low FG%; Hill is consistent but not a high-volume scorer; Rose (if healthy) would be a good player to have but still, the quality of players you would be giving up would not justify the trade... IMO
Hope this helped! I personally would not accept either of the two trades.
