Doom is in a fairly unique position given that most people know him for the disfigurement. While I would prefer a more modern take on that it does come with its benefits.
Having Victor disfigured enables them to employ the "Darth Vader" method of using a stand-in for the physicality and then dub over him. But on a narrative level it also allows some freedom with what Victor might look like under the mask and or how he sounds. Whether he's actually disfigured or has a scar can be up for debate until the reveal. And then you have the power that Doom can transfer his mind into someone else. Meaning that any potential time Victor is unmasked he could be anybody. And even then you have the Doombots which could look like virtually anything.
Doing it like Darth Vader would work here but especially for the sinister quality of it because you never know where and how Victor will show himself, and even if that's what he really looks like, disfigured or not.
The buildup to Victor's full reveal can be glorious given that we might only get small snippets of his full power or that we never see the actual Victor. Meaning that the audience is left in anticipation and fear over what Doctor Doom actually is. If you ask me, that's also a great way of tackling the various incarnations Victor has had over the years. You can redesign Victor each film knowing it may or may not even be him.
While I don't think we need a big actor, I wouldn't be against Adam Driver as Doom.
