An Machina Domini Interface Cockpit (IO, p.116) allows a 'Mech to not use a Gyro during construction. Removing the Gyro frees up 4 Critical Slots in the Central Torso for a grand total of 6 free Critical Slots. A Clan XL Engine adds 2 Critical Slots to each Side Torso (TM, p.50), while an IS XL Engine adds 3 to each side.
1) May a 'Mech with a Interface Cockpit and an XL Engine place all 10-12 of that engine's Critical Slots in the Central Torso?
