I think Stront could go on without Carlos, but without John and Carlos? Tough
As others have said though, if it was the herald of a new way of working these kind of things, with some level of financial recognition to the original creators, then who am I to stand in the way?
Certainly from an artist point of view, MacNeil and Weston have both shown they could take it somewhere respectful but different. I think replacing Wagner at the same time would be a huge ask, though if care was taken to find a sympathetic writer to go with a sympathetic artist
Going for "past tales" rather than continuing on from with Kenton and Johnny might be better as a start though we all recall the minor griping about that when it was the dream team doing it!
