I... I guess so, but I don't know why you would. In any case, there's varying degrees of blindness and deafness you could go for. A Jaeger with no conpod windows would basically need to rely on sensor checks constantly to navigate (it'd probably get away with better conpod armour, so that's one advantage I guess). A Jaeger with no sensor suite could maybe manage with the mark 1 eyeball, but would be completely limited to (basic) sight and touch, not to mention completely unable to make sensor checks (at best, you'd have to piggyback off other jaegers' checks). A Jaeger with no windows and no sensor suite would only have a meaningful chance of hitting anything if it were in arms reach, and would require constant communication with other jaegers or LOCCENT to even try to, say, chase down a kaiju outside melee range, or find the location of an ally.
Basically, in terms of usefulness/viability?
- yes sensors, no windows: awkward, but potentially doable. Proper armour for conpod in exchange for constant checks for anything outside melee. High Dex/sensor augs can mitigate this. Sensor damage is terrifying.
- no sensors, yes windows: sort of functional, as long as it's fighting during daytime, in an open space, on land, and there's only one foe to address. Can't make sensor checks, and is completely deaf. Conpod as vulnerable as always, if not more so due to nonexistent sensors.
- no sensors, no windows: 2500 tons of awful.
