"In 34 states, the governor makes an appointment to fill a U.S. Senate vacancy until the next regularly-scheduled general election. At that point, a candidate is elected and serves for the remainder of the unexpired term, if any. Table 1 lists the states where the governor appoints a U.S. Senate vacancy replacement."
WV is on that list;

If they break the law, it will be more ammunition to be fired in the next elections.
I’m sure that the governor will take care to follow your rulings to the letter. Well, maybe not. More likely, he will do what is in his own best interests and find some lawyers who will paper it up to look good. It may be that they do exactly as you say, but only if it suits the governor’s ambition. You do remember when Nixon carried the State of West Virginia over John Kennedy don’t you?
