My main issue here is that a lot of people have wanted to do this, and either failed or given up because of the large amount of problems to solve with a modular laptop/phone/anything of that nature. So either you are naive to how hard this actual is to do because you don't understand it at a high level, or you have solved some very hard and interesting problems, and not taken the time to share how you are doing it or at what level of competency you are at. Either way, the proof is in the pudding, and I wish you the best.
