Would it be overkill...

...if when I send the application in that I copied both my High School Diploma and University degree to prove my English language component? Or just the copy of the degree would be enough? (both are from the US).

If you have University Degree that means you have crossed High School Diploma....Just send your degree certificate alone...my 2 cents...

Sending both does not hurt. it would be a plus point. Even though your university degree will have higher credibility as a english language proof.
