Didn't the original story have Madeline (Miss America) dying in child birth and Bob Frank (The Whizzer) being so stricken with grief that he runs out the newborn twins? To add insult to injury Bob Frank dies at the end of the Avengers issue (i think it was a Giant Sized special). That's not a good way to treat either Pietro and Wanda or the Golden Age heroes. It's Padme Amidala levels of selfishness, with regards to Bob's actions. Just give birth to two babies but end up dying because she's lost the will to live without Anakin. WTF, mate.
Honestly, I felt tethering the Maximoff twins to Magneto made more sense for several reasons. 1. Magneto did rescue them as children right as their powers began to manifest, from the mob of villagers. 2. The history they had together. Twisted at times as it was, but then again, humanity has never been cool with mutant kind. Even when QS and SW joined the Avengers. 3. At the time Magneto was just a bigger deal (and still is) in the larger Marvel Universe compared to Miss America and the Whizzer.
