Theory on heralds/ Odium's plan

[SirWatermelon]

So, I just finished my oathbringer re-read and have come up with a theory about the heralds.

Spoiler

At the end of oathbringer, after Moash kills Jezrien, the other heralds feel as if their soul is being torn. Souls tearing has been referenced before, by lopen talking about binding a spren, and by various shards mentioning communicating with hmans who have damaged souls. 

my theory is that the oathpact bound together the souls of the heralds, part of the reason is probably so that they could share the pain of torture, but also it is possible that this was also done to cement them together to the oathpact. Oathbringer spoilers.

So, after Moash killed Jezrien, he accepted his honorblade. is it in anyway possible that after he was murdered, Jezrien's spot in the oathpact was opened, leaving space for moash's soul to wriggle in. and that in doing so, a new oathpact, with Odium is formed. this is under the assumption that in accepting Jezriens honorblade and being reporn as Vyre, gave moash the ability to become a herald anyway.

The second part of my theory is that Odium will use this to make/ replace the heralds, meaning that in order to stop the fused from returning after death, odium's new heralds would need to be dispatched.

thoughts? Any Wob that make or break this theory, or any things that you can point out?

I cannot think of any Wob that disproves your theory, but I think that if a new person joined the oathpact the other heralds would probably notice. So when stormlight 4 comes out in November we will be able to see if your theory is true or not.
