I don't think it should be a problem, just make sure you bend the hoses smoothly without kinks so that water can flow. IIRC, the 2.5 / 4.0 uses the heater core as the thermostat bypass, so it needs to allow water to flow to let the engine warm up evenly and to warm the thermostat so that it will open at the right time.
