Default Upsizing Engine and Fuel Tank

Aloha RCU Flyers,

I have decided to incorporate a FPV system into one of my Avistar Elite planes. Depending on how much weight is ultimately added I may need to upsize the engine from the current and recommended .46 OS glow engine to a .55 OS. I would also want to upsize the tank from the 8 ounce to a 12 ounce. My question is are there any hard rules about matching a certain tank to a specific glow engine size?

I have read through many threads on changing fuel tank size and the responses are varied. I am seeking a little more clarity on this.
If it's relevant I am also considering the 10cc Evolution gas engine as an option.
