Tauros venator as Field ordnance battery??

So I love the tarous venator model and I want it, but i want to use it to proxy something that j can use in game.

Obviously with some minor conversions to make it fit tbe army theme and get the weapons to match, I was just thinking of using lascannons.

Just curious on the more experienced people with the hobby and maybe tournament scene if they think it could be a plausible idea, if dome correctly
