TII rotor housings are wider than 12A rotor housings. You would need a TII eccentric shaft and rotors, flywheel, counter weights etc

Again, NO you cannot without modifying the housings. The housings on the first gens have the coolant seals in them, as the 2nd gens have the coolant seals in the irons.

12a irons (no coolant seals)
TII Housings (no coolant seals)

You will find out pretty fast where all your coolant goes.
