consensus – How does the blockchain know if its block hashes have been tampered?

I’m dealing with some problems to finally understand how implicit consensus works and I’ve come across with one question. Suppose the following:

A malicious miner proposes the following block to be included somewhere in the middle of the blockchain. If he just copies the value of the previous block’s hash pointer in the new block’s header, and recalculates the following blocks hash pointers till the end of the chain, by coping the same header in each block in the original chain, wouldn’t this blockchain be as valid as the original, considering that the new hash pointers match with the content of each previous block?

A way of trying to clarifying myself and answering to the question was to think of the implicit consensus. Could it be that the other well-behaving nodes will deny this proposing block by storing a copy of the previous state of the blockchain and comparing the old blockchain with a new one?
