Why do you want to remove IPv4?

Dual-stack means the systems run both stacks. What I understand from the
above is you do *not* want dual-stack, but rather to have some subnets
that are single stack ipv4 and others that are single stack ipv6.

But why? What is the goal of that?

If you intent is as above - to have different segments where some are
ipv4 only and others are ipv6 only that can inter-communicate, then yes:
In that case NAT64 is really the only option.

However, NAT64 does not have to be done on a new expensive cisco box.
You can implement that on a linux based gateway on a PC or VM too.

I'm still not sure why you would want to. But you can :)
