Homebrew frame ideas

I am in the middle of concepting a homebrew frame (for funzies)

I've decided to make it a barbarossa alt frame that centers around ignoring or bypassing the ordinance tag.

One frame trait is the ability to fire ordinance weapons after firing at the cost of 2 heat. After that I'm drawing a blank. It will probably be a size 1 or 2 mech with move 3 and 1-2 armor.

Any further ideas are appreciated. Or even feedback on the current idea.

Theme of the frame, mobile artillery.
