The props for the Q500 are in plentiful supply and available at several sources. The props for the Typhoon H are smaller and different pitch than the Q500 props. The motors for the Q500 and the Typhoon are physically and electrically different. You don’t have access to the parameters (PID settings) that allow the flight controller to fly the aircraft without burning up the motors or ESC’s.
If you really want to build your own you should explore the world of FPV racers. The software and firmware are mostly open source and not locked up the way Yuneec and other off the shelf drone systems are. A little reading on the subject will let you know you can’t just bolt a new motor and prop on a frame and expect it to work.
