For example, in the phrase:
John told Mary something unexpected and thoroughly unsettling – but in the best way a person can be unsettled
Is there something wrong (meaning-wise) with this? Can the words unsettling and unsettled be used this way? (By the way, I have a slight feeling the second occurrence in particular is a bit off).
The context, in case it's not evident, is John telling Mary something she didn't expect, something John wouldn't normally say, which made her feel very surprised, but in a clearly positive way.

I don't think your example can use unsettled in a positive way, because it appears to use the definition of unsettled meaning "Nervous or worried"

However, one can imagine situations where someone might desire or prefer to be unsettled, in the simple sense of "not settled", eg
"I was an Air Force kid, and moved constantly. Some kids would have hated it but I loved my unsettled childhood - I got to see so much more of the world."
