", and" is not necessarily wrong (or superfluous), and isn't in this sense. "As well as" has a specific meaning, which doesn't fit in the majority of the instances where you added it. Should the use of the comma be incorrect, you can "fix" it by removing the comma.

In short: don't change it. It's not wrong. End of discussion.
