my idea is to have a split campaign of a tech priest hunting tech and tech heretics and to have an inquisitorial squad hunting heretics occasionaly meeting and fighting the tech priest squad wat do you think?

Well, just one tech priest? Any particular out-of-game reason for the solo campaign and the group campaign?

Also, why are the Tech-Priest and the Acolytes fighting?

It could be a cool idea or it might not, you didn't give us a lot of information to judge by.
