Android splitview/region presenter with MvvmCross

Android splitview/region presenter with MvvmCross

My goal is to create an Android UI window that displays three regions:
navigation, main, and popup. The navigation and main region will function
as a split view. The popup region will be centered in the screen and
overlay the other two regions; it will also only be visible part of the
time. Ideally, I'd like these regions to host fragments that are
dynamically changed to display different layouts and view models based on
user interaction. And, all of this should be accomplished without breaking
the MvvmCross bindings.
I've got something that works, but it feels a bit hacked together. The
current implementation most closely follows resource 1 below. Each region
has a dictionary. All of the fragments are registered with a dictionary
based on their target region. This is done from the activity. The activity
also takes care of inflating each layout and associating it with the
correct view model. I'd like to change this so that MvvmCross can do more
of the work.
Is it possible to create a custom presenter, in Android, that is a mix
between the dynamic fragment layout from resource 2 and the iOS custom
presenter shown in resource 3? Just to clarify, I want to specifically
define where each region will be displayed using a layout. Then I want to
dynamically fill the content, of each region, with different layouts and
their associated view models, at runtime.
