The crashed Hawk has its own module that's used while you are on Lehon (ebo_m41aa vs the regular ebo_m12aa). That's the only reason I bothered with it, since placeables are out due to the K1 row limit bug, so it was done as room model. That meant altering the layout, and I didn't want to screw with the regular Hawk. For the monitors you could conceivably do the same thing and handle it the same way - the OnEnter checks the current status and plays the appropriate room animation. For the hologram, it plays something like the above videos, then once you repair the hyperdrive it switches to a version that shows a solid green hyperdrive in the hologram (i.e. plays a different room animation). Once you head to the Star Forge you go to a stunt module for the appropriate Dodonna message, and that uses the regular Hawk layout (and different scripts), so the hologram is gone.
Regarding Salk's now edited message, there are two different hologram Hawk models used. The first two videos use a more simple Hawk model from TOR (it's one of those mini pets). The third and forth videos uses the actual K1 Hawk, scaled down (thanks to @JCarter426 for saving me the trouble of having to kitbash it).
