Imaginary numbers could probably have been more seamlessly integrated into mathematics if the system was rewritten. But that's the beauty of math, it's built upon what was found out before, generations and generations of curious, intellectual, (and historically male, and rich) individuals building upon the shoulders of the previous generations. Sadly, there were many people who did not have minds that could accept things that they couldn't understand. I'm sure if someone were to find the solution to dividing by 0 it will not be accepted for a few hundred years. And until then, it will exist in the 2D plane as an asymptote or removable discontinuity..
