Good idea!... lets start with why the dual parent citizenship + birthplace is important.
Hint: Think in terms of our founding fathers trying to prevent intentional userpation of the office by a foreign power.
Note: Because of our free and open electoral process, NO set of qualifications we could impose on candidates would be totally foolproof against intentional foreign exploitation. Even using the birthplace + dual parent citizenship can be exploited. This is why years of residence are also specified in constitutional law.

Well that didn’t work.
