It would be a nice use of the this new tech.
While your idea is nice, LN is still beta, so it may not be safe enough for the average Joe.
And not all campaign participants are experts.
So for now I'd be happy if all campaigns would use SegWit (!), which is already old tech and still insufficiency used, and leave LN mature (and get "released") before using it for everybody.
Agreed, even I don't know how much I will need to open a channel and to ask a friend to do so. Let's give LN some more time. I'm sure these small things will go on automatic and then it will be easier to understand.
