Drawing Capito in with Rahall is probably the best way to get her to take that risk and run for Senate or Governor.
The question is, would Democrats want that? 
I'd have to question whether someone that risk-adverse when it comes to political ambition is really worth appeasing. By the time she figures out that the map disfavors her and acts, she won't have as easy of a time clearing the Republican primary for statewide office [and given her moderate profile...] and that route becomes increasingly perilous too.
