I think those at the head of Bitcoin should be pushing for more forks
Bitcoin doesn't have any heads. That's kind of the whole point of decentralization. Forks are being decided by some random members of the community.
until Bitcoin is unforkable and putting through dynamic ideas for totally transforming Bitcoin
This will never happen. Bitcoin is open source and no matter how many forks emerge out of it, or it emerges out of, it will continue to be forkable.
Bitcoin vote among the top 10 decentralized private cryptocurrencies who's (open-source) technology to outright copy
The problem with this is there's really no way for the community to vote in a fair manner. No one knows who everyone else is, so identities can't be checked, and if identities can't be checked, then I wish you luck in finding a way to stop people from voting multiple times. I would not be opposed to copying ideas for as long as they fit in the general idea of what Bitcoin is trying to do.
A clone would be created. The exchange rate of both Bitcoin and the donor blockchain currency would be locked at the time cloning begins until the process ends. Then Bitcoin would flow into that clone through a cryptocurrency interface. Perhaps there is a future where Bitcoin is so flexible a clone is not necessary and Bitcoin can simply flow into another block chain
This would be a sound idea if there actually were a way to vote. This problem is why we're in this Segwit2x mess in the first place. With no head, and with the community fighting amongst themselves, it would be very hard to come to a resolution.
