Would a check valve in the hot line solve the problem?

In the case of a cross over at a faucet, probably not. In order for a check valve to work, the pressure on the back side of the check valve has to be greater than on the entry side, thus causing the valve to shut off.

In a water line, cross over situation, both sides of the check valve would be equal pressure, leaving the valve open, allowing water to flow back and forth.

Don't think it would benefit anything. Just make sure the actual faucet handles are both turned off. Much easier and simpler!

wouldn't a check valve in both inputs to that faucet solve this to?

That would work, but it seems the easier fix is just get in the habit of closing the valves. Check valves can restrict flow, and I must have replaced that check valve on my HW tank 10 times and always while on good vacation time.
