I agree - for those who haven't read it, the original Vision & Scarlet Witch mini-series does a great job of pointing out just how much these two are inter-connected to the shared universe - culminating in the reveal that Magneto is Wanda's birth father.
Wasn't there a Disassembled-era interview where Bendis said he asked Queseda for a list of characters he could kill to wipe away the old guard? Seems to me I remember him reacting with glee about how many characters (and with big names) were on that list.
The idea of a "kill list" does seem familiar... but I'm not sure that it had to do with Bendis/Disassembled. It does seem familiar though.
