From a quick glance at the mpm-itk source-code, it does its magic in at
the headerparsing phase, so your attempt at using that phase to alter
it's behaviour was a good one.
/* set the uid as fast as possible, but not before merging per-dit
config */
ap_hook_header_parser(itk_post_perdir_config, NULL, NULL,
APR_HOOK_REALLY_FIRST);
Unfortunately, it seems to pick APR_HOOK_REALLY_FIRST as precedence,
which makes it run /before/ your code, in the same phase. So, even
though you actually succeed at changing it's run-time configuration, you
do it too late, and it doesn't even look at it.

Yes, as expected, and it uses a published API to do that.

Except for my above explanation, this would work just fine. I would
however caution about using this kind of mechanism to alter run-time
configuration on a per-request basis. This comes at a non-negligable
performance impact, if that's important to your usage scenario.
Ideally, like in the server_admin() case outlined above, mpm-itk
could/should expose an API to allow for changing the userid/domain.
You could try and use PerlMapToStorageHandler as your phase, since it
happens before the PerlHeaderParserHandler phase.
