Glad you're going through this as an exercise, but my understanding has always been that even for something as simple as getting your name changed, you should just get an "agent" to do all the work for you. As you noted, almost every paper you needed is essentially unnecessary, and all you need to do is make sure that someone in the chain can ignore many of the useless requirements. This also means you probably have to pay the bribes as part of some "package" I suppose.

Is your goal to open a factory, or is it reform? I'm glad if someone's trying to reform all these useless ideas and everything, but it doesn't exactly make sense that you couple basically two fundamentally different problems though. If you honestly want to get into manufacturing in India with any real practical timelines, you better get used to paying bribes as cost of doing business. If your idea cannot work with the extra cost of 10 MBP level bribes, better don't bother at all right?

An anecdote I have of relevance: I used to draft letters for my father in the 90s for his company. Once I mistyped 1997 as 1979 in a letter. The licensing authority fined his company Rs. 3,00,000 for that mistake. That was 10% of his annual revenue back then. That's because he had negotiated with the person a month back to not increase his bribe. And hence the agency used this as leverage to get a higher bribe.

Point is, you are trying to fight such a fundamental force and way of life in India, I will not bet money that you will succeed in this route, though I sincerely wish you would. Even if you do everything right, they will invent a problem because now you've hurt their ego on top of their pocket. Hell, if you actually start succeeding you should probably start worrying about personal safety as well (I would if I were you), because I doubt India is actually developed enough to ignore the worst case scenarios you can imagine in a corrupt society like this.
