These seem mostly to be Greek text issues. The variety among some of the Greek texts is shown plainly here, using Galatians 6:15 as an example:

It doesn't seem to be much of a corruption so much as it is a choice of which texts to lean towards.
If you say all these differences you brought up are indicators that the Recovery Version is corrupted, you would also need to say that almost every other translation besides the KJV is similarly corrupted. In many of these examples, it's the KJV that's the unusual one from the majority of the rest.....not the RcV that's the unusual one.
And if you want to say that all other translations besides the KJV are "corrupted", then......this ends up being just as problematic as the LC top dogs who think that all other translations besides the RCV are "leaven".
Definitely not defending the RcV, but.....I don't feel like this particular "fight" has a lot of force behind it. There are other translations that genuinely lose critical aspects of the gospel message. I don't think the Recovery Version is really one of them. (speaking of the text itself here, not the footnotes)
As one of the "so many today" who questions whether Jesus is God, Ephesians 3:9 is not one of the problematic issues at all. There are other unadulterated verses that show God created through Jesus, so Jesus being part of the creation process is not lost by this "corruption" of Eph. 3:9.
Also......your preferred translation, which is "...in God, who created all things by Jesus Christ" does absolutely nothing to bolster the case that Jesus is God Himself. The sentence structure heavily supports the opposite - that Jesus is a separate being from God entirely.
This will probably be my only contribution to this thread.
