The core itself just has a serial link to control it (would be over USB 2 using the standard analog output VPC), so getting control should be as easy as breaking it out, using a serial to USB adapter, and starting the GUI. It will also remember commands given, but if the initialization of the other hardware in your scope is giving the core commands, it could quite easily just overwrite whatever you set and go back to normal for it, since it would control the core just as easily.
You may be able to get the more visible highlighting results from either locking the autoranging to a specific place (if you have the option), or selecting a higher contrast palate for the visualization. I don't know if the scope has environment input options, but messing with those could also be worth a try.
Since the core itself is export restricted if higher than 9Hz framerate, it may be trickier to get the VPC from the US, it's probably best to go through a local vendor to make sure there are no issues. Not that I think the VPC itself is restricted, but as it's an accessory to something that is, it may count as restricted to an online vendor.
