No they can't. 24 states have "Faithless Elector" laws. Look it up.
Those states can speak for themselves and could, perhaps, recall and re-appoint but they do not supercede the Constitution which requires certain dates specific be met. Those dates will not be changed. There is no requirement in the US constitution that electors have to vote. They are complete free agents.
Electors were to be elected without influence by political parties (”factions” the Founders called them) perhaps with no idea who they were going to vote for. They were to meet in each state and make a decision who to vote for not follow the dictates of a political party or even legislature.
Fear of factions was a driving force at the Convention and devising a means of preventing and thwarting them a major concern. But it only took about five years before Jefferson and Madison created the first political party to stop Hamilton’s program adopted by Washington.
SCOTUS may have an opinion on that. States cannot willy nilly change the Constitution.
