sup guys, i started reading about the rotary engine,

see me and the guys are designing a formula SAE car, so my job is to take care engine matters,
so i had an idea, and wanted to know if its stupid before telling the guys :) , can i use 1 rotor engine ? i mean if i have a 2 rotor rotary engine, can i use just one rotor ?
coz we r restricted by the volume of the engine, and it should not exceed 610 cc, and i happen to have an RX-7 2 rotor engine, and each rotor is 576 cc, so, am i...stupid ? :)
