My thoughts on your theory.

1: The island could've broken off to become an iceberg.

2: Showa Godzilla suits are never consistent.

3: See 2.

4: See 2.

5: Godzilla's behavior in the Showa films are not always consistent. In Ebirah, Horror of the Deep, Godzilla took a liking to a human woman, which has never happened before or since.

6: See 2.

7: Godzilla's roar has also changed in the Heisei series.

8: Godzilla was already shown to tolerate the presence of other monsters by the time he teamed with Anguirus.

9: Well, it was a direct sequel. Also, he wasn't exactly the Monster of Justice like in later films. He was still a God of Destruction until he became a parent.
