If you do switch you’ll need custom hoses. Then there’s the issue of the compressor which will need more custom hoses. The issue with using a service like cold hose is your hoses are made of bent steel sections and rubber sections. They probably cannot recreate the bent metal tubes with off the shelf components. That’s why you need to braze on barbs or male insert o-ring fittings on the metal sections then connect them with rubber.

It’s going to take a plan where you determine each element your system is going to have. That’s why I say don’t come up with something in the heat of the moment. Fix it now with a hose, recharge, then plan your dream system in the winter when you have a cool head.
