Hmmm, yeah, we've made some use of commands for random values. It's not really that hard, but the game doesn't natively use randoms in event code (with the exception of one command which randomly skips the next line). That command could be modified to take a parameter, or to simply generate a random number for later processing. Generating's the easy part; figuring out how to make it process those numbers and seamlessly flow as a more realistic simulation of how decisions occur-- that's hard.
But yeah, it's possible, up to the hardware limitations, which wouldn't be a problem for the simple cases.
