Finally got something!

I just had a brain fart on what I want to do with the heating and cooling of the cabin.
I want to replace the heating element under the dash with a cooling version (i.e. running an AC pump and keep me cool in summer) and first I wanted to do an electric heating element behind it, so I can still warm up in winter.
But then I got thinking that it would draw more than my alternator can reliably supply, so why not just keep using the same water system to heat the cabin, just move the radiator position.

Now I still have the original plastic scoops on the front to channel air into the cabin (driver and passenger), so why not just put the radiator in front/inside of the driver scoop? I can then introduce a 12v hairdryer fan to keep hot air moving when I'm stationary, and a spring loaded dump valve to waste heat when I close the vent inside.

I get to make space for an Air conditioning inside, and keep using the hot engine water to warm up when I need to!
