A problem with CB Super Activity Module is that is uses a licensing approach that is incompatible with JED Guidelines and/or the GPL License. I'm not as familiar with how SIMGallery handles it's notifications.
I suspect however that there is no simple out of the box answer. We'll see what Stephan says, but probably nothing short of installing it in a development environment and sorting through the interfaces with all three system will give you an idea of how challenging the integration effort will be.
Basically every module/component can be modified in a way that uddeIM PMS is used.
The simplest way to do this is to add 2-3 lines to include the uddeIM API and to send a message through the API. How to send a message using the API is explained (with example) in the FAQ.
