For god's sake NO, that would be the final nail in the coffin of Google owning web standards. 99% of users would choose Chrome because it's what they recognize most, and I assume in this scenario you're imagining this is actually different browsers using their own rendering engines.
I don't understand why in this world of Google's near monopoly on the web, people are more focused on government intervention to prevent Apple's pithy 9% marketshare for holding back poor Google.
