How hard it would be to make a sensorless BLDC motor controller using just discrete logic ICs?... With field oriented control :D

I've made this hall emulator (basically LM339 comparing virtual middle point with phase voltage) but it worked like shit because ebike controller PWM was coming back through motor into halls and i couldn't really figure the fuck is going on since I don't have an oscope.
