I agree, very nice of Christine to reach out. It's a shame it had to come to this it but personally I would hope LB never goes back. What's the point? The light has already faded. Lindsey is doing well on his own and expressing himself and music in a way that brings himself and his fans great joy.
On the other hand the lure of one last reunion tour (assuming there is such a thing ) may be too hard for any of them to re$i$t. Especially a certain dude named Irv Azoff.
Should this turn out to be the case it won't come as any big surprise nor will the hefty price tag attached.
