No, the Death Star plans in the original verison of ANH is inaccurate and creates continuity errors, so that would stay. Knowing Ady, I imagine we won’t see anything about the Death Star at all in the prequels.
Also knowing Ady, he’ll probably insist on building a Yoda puppet to replace the CG, but hopefully we can talk him out of it. 😉
Regarding Yoda, maybe by then he will be able to take images from ESB and “blend” if you will those images with the animations of CG Yoda.
There are definitely some FX shots in TMP especially than need some help/haven’t aged well.
