What if: Imu's fruit is Nika's other, more evil form?

In Elbaf we are introduced to the idea that Nika can be a great savior or a great destroyer.

So this got me thinking, what if the reason Imu hates joyboy because he is the polar opposite of joy? Instead of freedom, he is dominion?

Unless luffy has access to these other forms as well, it is entirely possible that since devil fruits are human desire made manifest (that we know of, anyway) instead of one fruit having multiple personalities the personalities split into different fruits.

Imu naturally hates joyboy because they are destined opposites. One believing in salvation and the other obliteration. He hates him because he thinks his view of the world is naive, and joyboy naturally wants to defeat Imu because people should be free.

Im not amazing at theory threads so I cant make it all fancy with pics and such, but that is the theory.
