You can do that kind of change in your own Bitcoin-compatible client, but y=
ou cannot be sure that other people will run that version and that it will =
shut down when you want. Many miners use their own custom software for mini=
ng blocks, the same for mining pools. There are many clients that are compa=
tible with consensus, but different than Bitcoin Core.
Also you should notice that Bitcoin community make changes by using soft-fo=
rks, not hard-forks. Backward compatibility is preserved as often as possib=
le and there is no reason to change that. Any change can be deployed in a s=
oft-fork way, even "evil soft-forks" are possible, as described in https://=
petertodd.org/2016/forced-soft-forks. I think that kind of soft-fork is sti=
ll better than hard-fork.
