Yes, TVI would do it if you have one, or a second Cortex.
But I’m curious why you want to do this. I would say that the best way to use Memory Palace with Cortex is inside the Cortex compositor. You could use it to key your original source (dry) over your modified image (wet, from Memory Palace out.) You can also use it to layer analog gradients and solarization back in with your Memory Palace output (looks wonderful!) Or to introduce a secondary feedback loop around Memory Palace using the analog compositor.
