If I recall, the whole purpose of the World of Remnant videos is to give the animation crew a few weeks to do more work on the episodes without the pressure of "This episode is due to come out at the end of this week!!" That would be why the World of Remnant videos are 2D animated. The 3D animators get to devote all their time to completing and polishing RWBY episodes.

So, if we ever get something else that replaces World of Remnant, it'll be simple 2D animation like WoR, not 3D mini episodes.
