Well I for one also think the cockpit should be required not optional, but that there does need to be the ability to look around the inside, that way it does make you think more about what to fly, and as for the Y-Wing thing, it'd encourage teamwork to win, since a strict bomber should NOT be flying solo, it should have some cover fighters with it to prevent it from getting destroyed easily.
In Star Wars Galaxies I use fly quite often and although I no longer use TIE's, it took awhile to get used to them since you only have a forward view and an upper view thats quite hard to use since its for small slits in the top hatch. This adds greatly to immersion and once again would add to teamwork since it'd help prevent TIE's from going out solo, they'd pretty much HAVE to use wingmen to stand a chance, or be EXCELLENT pilots.
So in the whole long winded thing...make it so you have to use the cockpit.
