Ares-more-like-Artemis sounds exactly like Excalibur which is an interesting ship but already needs some rebalancing or more playtesting with a regular crew who can work out her advantages and disadvantages.
Broadside does sound interesting but i hate the 360 degree point defense.
I also do not see a problem with allowing her to have the opportunity for fighting both sides. She has to give up manual targeting for that. I would propose a standard beam port and starboard with a 22.5 degree arc and also identical or lighter fore and aft bow- and stern-chasers. Then also give her broadside “carronades” with higher damage but shorter range, say 600-800. That means she has to manoeuvre for drones, but has a possibility of getting heavy close damage unlikely to be useful for fighting both sides. she will always struggle to respond well because targeting will be difficult as soon as the enemy starts to turn
