As my ole body shop instructor used to say, "With enough time and money we can take your old door handle and build a new car around it."
Can it be done? Yes. Will it cost two arms and a leg? Yes. Besides several critical components, you shall probably need to replace a couple of wire harnesses and probably the dash--all due to the sensors. The best suggestion I have is to buy a factory manual and compare the wiring for the auto air vs the regular unit. You also need to determine exactly what is different in respect to components and this won't be easy as you will probably need a Crash Estimating Manual for part numbers for various items. You could, of course, by way of the wiring diagrams alone "mickey mouse" a conversion by running various wires, but I would not recommend this.
Another idea is to find a suitable wreck (a vehicle which can be sectioned giving you the front half of the car) and then slowly substituting part for part, wire harness for wire harness, etc.
There is not a suitable vehicle outside of the country which could be bought and legally shipped into your country?
