Sound like a great idea.
Could you provide some details on how you did this. Maybe some pic's?

You can disconnect the heater hoses at the engine and loop a hose connecting the two or disconnect them at the firewall and hook them together with a splice nipple. Some cars have 2 different sizes of hose so you will need the proper nipple for that. Usually 5/8 and 3/4".
