You're right that the iwad dialog happens so early that no other pk3 has been loaded yet. Unless there was added something explicitly loading additional engine pk3s you won't really be able to override those assets.
About bootlogo.png, I think the reason GZDoom doesn't have one is simply that Graf might not have had one at hand. Now that the resolution limitation is lifted in vkdoom its quite possible he'd just have grabbed one of the standard logos already available for GZDoom, but at the time it would have required some work to adjust it to fit the old resolution limitations. I can't speak on Graf's behalf, but my guess would be that he wouldn't mind getting a good looking logo if provided. Even the logo in vkdoom is just something I hacked together - there are people (like you!) that are so much better at creating this kind of thing than us developers.![Smile :)]()
For Hexen et al it uses startup screens made specifically for those games. It is indeed showing their game specific assets in the loading screen. They are fairly limited in what they can do however because they uses the same lump formats as the original games.
