A complication is that fuel excise is a federal tax - and any feasible replacement for it in EVs would have to be a state tax. Best of luck on getting states to all agree to collect money for the Commonwealth, or to refer powers to the Commonwealth.
The powers of the Federal government to tax are limited, and historically states have been very reluctant to assist (and the Commonwealth has also been very jealous of state attempts to trespass on their powers, for example in state attempts to emulate excise a couple of decades ago.
Certainly, the states could impose an annual tax or a mileage tax on EVs, to make up for the loss in excise - but why would they? That is the Federal government's problem, and they have neither the power nor the mechanism (vehicle registration) to do it.
