Please help ! circular pattern without duplicating the main flange?

Hi guys so I have this weird cone shape that I want to array into a circular pattern x8 around the inside of the flange. I have to choose bodies for some reason (probably because the solid body is merged to the flange) but I do not want the flange to be duplicated. is there a way to array this without duplicating the flange? please take a look at the model attached

side note: if I do not merge the the feature then the design wont work as it is. Please advise.
