If you mean downloading The Bitcoin blockchain, as shared by all Bitcoin users: then yes, that's what Bitcoin Core does automatically when you start it: download all the necessary data and reconstruct the blockchain.
If you mean create an altcoin, then the answer is that depends on the skills of the individual. You need to be a very skilled developer to create your own coin and make anything useful out of it. Many have tried before, and pretty much all have failed.
In your case, you're about to create a private blockchain, which defeats the point of having a blockchain in the first place so you might as well grab an (No)SQL database. Also: a coin needs users to have value, you're not going to pursuade any users to join your coin. They might as well stay on PayPal.
Miner are (can be) anonymous in Bitcoin, which is very much a requirement for the whole system to have a chance at working at all.
