I don't like the idea of changing gun arcs or changing gun positions on the Squid. It's a fast ship and with the constant damage on armor and engines you can't always use two guns at the same time during combat anyway.
I fear, if this were to happen, people would just sit in front of their target and use the most boring combinations the game has to offer (e.g.: gat/mortar). If you wanna use gat/mortar just turn and have an engi ready, if not, go away and come again another day. The Squid is no brawler, the low hull armor makes sure of that.
However, since it's so low it's armor is that low, I do believe that increasing the maneuverability, may it be verticle or horizontal, is good way to increase the number of squids on the battlefield, especially with all that phoenix clawing...
