Mechs can have Dual Cockpits (
http://www.sarna.net/wiki/Dual_Cockpit and
http://www.sarna.net/wiki/Command_Console), I just don't know how the hell they would translate to MWLL or if they would even be worth it.
Dual Cockpit:
* A Piloting Skill roll to avoid falling is required only after suffering 30 points of damage in a round (instead of 20);
* Improved evasion capability grants better movement modifiers to hit a unit equipped with Dual Cockpit;
* Similarly, modifiers to own fire from own movement are less severe and a secondary target may be fired at with no penalty.
Command Console:
"In game terms, the Command Console occupies the free critical slot (#4) it the head section. Since it is a fully functional cockpit unto itself, it can take over if the regular cockpit (#3) is destroyed or the pilot is incapacitated, provided of course that the Command Console is manned; in that case both cockpits must be destroyed to incapacitate the 'Mech. "
"If the secondary MechWarrior is not piloting the 'Mech he can make use of the command and control functions of the Command Console to add +2 to his side's initiative. This is not cumulative with other Command Consoles or mobile HQs, but it is with the initiative bonus from an enhanced satellite uplink communication system (if available) and no penalties apply for the latter system while the Console operator is not operating the 'Mech himself."
