Not sure how well behaved VST is in this regard, or if this covers the
use cases you have in mind, but one way around might be to have your
plugin wrap (ie host internally) the plugin(s) you want to control.
That way, you relay all communications between the host and the
wrapped plugin, allowing you to modify, redirect, discard or add
information as needed.
Could be quite some work, although there might be some shortcuts if
all you want is to "transparently" wrap one single plugin.
