I have this big transistor looking thing that I pulled out of a (inverter, laser power supply, microwave oven, dishwasher, killer satellite, etc). Can I build an OLTC with it?

Right now we believe that IGBTs are the only semiconductor that will work in the OLTC. But nobody has ever tried making one with MOSFETs, thyristors, triacs, sidacs, etc, so we can’t say. Note, the IGBT needs to have a diode between emitter and collector. Some IGBTs have it built in, if not, you have to add an external diode with similar voltage/current ratings to the IGBT.
