Any way to "inject" an INIT block into a different module?

You can avoid the `no warnings` in the caller if you do something like
this:

    package Control;

    use strict;
    use warnings;

    sub import {
        my ($class, @args) = @_;
        warnings->unimport(qw<redefine>);
        # ... and install @args into the caller ...
    }

(See also ex::caution, not to mention Moose, which is where I first
saw that trick.)

I'm not completely convinced I'd want to do that -- it seems somewhat
icky to silently fiddle with the caller's compilation environment
without a dirty great indication that that's what you're doing -- but
it's certainly possible.
