It is most likely damage control because the Kang thing was derailed due to Kang’s actor being an abuser. RDJ is now a known and reliable actor for the MCU who is able to play a character like Doom and will most likely never show his actual face on acreen.

As long as Doom’s voice is modulated enough that it doesn’t sound like Iron Man it should work out fine.
