That's what I do, anticipating replacing the hoses every time. They're often hardened by age and will leak when pinched. But the hose is cheap and if it can't hold up to a pinch, you're better off with fresh, flexible hose anyway. Put some vynil tubing on the ends of the grips to minimize the risk of damaging the hoses.
