If it were me, I would have given Ben his memories back, and have him and Janine go on the road again, trying to stay one step ahead of Beyond. Sort of like the Lost Years with an updated spin. You could make a mini-series out of it or just put him on the shelf for a few years to bring back again when needed. It's silly that editorial thinks there's no place for Ben as he was; at least they could have reached out to DeMatteis to brainstorm on how to move Ben forward.
As far as Kaine goes, I think he was fairly well established during Yost's Scarlet Spider run, "all the power, none of the responsibility", and thankfully Peter David didn't damage Kaine as much as he did Ben during his dreadful Scarlet Spider run.
I like the idea of Ben and Janine as the Spider-family we'll never get with Peter/MJ, but that seems highly unlikely for the foreseeable future.
