This would mean that you take a full operating Bitcoin code, at least keeping the functions to read out the whole previous chain, which will rise up to 300 GB shortly. This 300 GB data would have to be distributed within your network forever, just for sharing the proportional airdrop in the moment of the fork. This airdrop could also easily be done by just providing the airdrop to the Bitcoin holders on the most common crypto exchanges as it's done usually. Even if it was really just a communication error and the SHA256 algorithm would be used generally after all: Who would download and care a 300 GB data corpse for life time just for your initial promotion? When BCH was forked "just" the blocksize had been increased from 1 to 8 MB and SegWit has been removed, the algorithm remained the same. The goal to increase the number of transactions per block was never reached. Actual BCH blocks remain generally around 120 kB as can be seen at the comparison of the statistics , while Bitcoin blocks have a multiple of transactions per block compared with Bitcoin Cash. One couldn't call this a real breakout. Let's take a look at the most successful implementation of the Proof of Stake concept: NXT, created back in 2013 and called the Next Generation of Cryptocurrency, one of the most trusted and serious crypto currencies on the market based on the PoS algorithm, came to the conclusion, that the size of their blockchain would be too large for a modern crypto technology. Three years later the Jelurida team created the Ardor multichain platform, where the users can create child chains just for not being dependent from the main chain for keeping the blockchain size small. The NXT chain is around 4 GB today, the Ardor main chain around 2 GB. This is a real trendsetting concept. Now you really think a hard fork for promotional purpose only would have success ever, compelling the users to distribute the fake fork with 300 GB data ballast just for your initial advertisement? Even if you would get running a quasi-fork in cutting off all historic data and just creating a new chain on top of a snapshot of the BTC chain, what would generally be possible - it still would be a fake fork with a complete other concept what the community never would accept as real Bitcoin fork. You project just abuses the name "Bitcoin" for promotional purpose, even if you ever would get a blockchain running.
