I'm customizing my yellow RiD Prime into a character called Corona Prime. I'm gonna change him from a firetruck into a cybertronian artillery truck and to do this I need to add some weapons to him. I'm looking to replace his sirens with guns, maybe the gun from TFTM Landmine if it'd bit and not look too small as shoulder cannons. I'm also wanting to find 2 firebot minicons to add to him as missile pods since he pretty much has minicon ports in alt mode. I'm wanting to replace his ladder with a heavy cannon of some kind though I want it to be shorter and lighter than his ladder. Thinking maybe a cannon from a gundam and slide it into the ladder mount maybe. Any ideas or tips on how to do this?
