With the tools available these days, part of me wants to -- but I know it's waaaay outside my skillset regardless of legalities -- export all the assets from SR2, SRTT, SRIV, SR:GOOH, up-scale and enhance them, and use UE5 to rebuild the *entire series* as a single cohesive experience that flows seamlessly from one to the next. But not stop there. Make it bigger. Better. Build more 'places' to visit, like more stores and diversions, distractions, etc. Incorporate the better elements and systems from each of the different games into a single cohesive whole. SRII's clothing-layering system, for example, or the ability to select different animation sets. I'd even add a way to customize more of the player's body proportions (via non-uniform scaling of character rig's bones -- which I've done rough mockups of in Blender). Oh, and semi-functional airports you could use to fast travel back and forth between the various cities of Saints Row once you've progressed far enough in their respective story lines. Functional trains in Steelport. Sadly, there are still some missing pieces of the puzzle, like the animation files for the obvious character actions, but also for cutscenes and etc, and while some of them wouldn't be too hard to recreate, the others would definitely be difficult.
In the fever dream where I could do all of this, I even wanted to figure a way to work in how AOM and the SR reboot fit into the grand scheme of things that doesn't throw away everything that came before it. Like throwing in 'blink and you miss it' moments where the OG Saints are watching NuSaints do their thing (ie, they're using Zinyak's time machine to mess with time).
