The Supreme Court has already placed strict limits on federal intervention in state elections. So it probably wouldn’t go anywhere although I would support an attempt at least.
The issue with (the most important parts of the) voting rights act was that it only applied to states with a history of racism. Expand it to cover all states and in theory the argument of the SC breaks down. Of course, they may well come up with a different line of reasoning, but a Democratic congress should at least try.
