It's not impossible.

You'd need to closely study the parts in an A/C system and find ones that fit in your car.

In Australia, b210, b110 A/Cs are very similar. They were sold aftermarket and factory option.

Late model B120/B140 (south african) Utes are a good source for A/C parts here in Australia.

Installing the A/C shouldn't be too hard. No harder than installing a car alarm and changing the headgasket.

It all depends if you can find the parts second hand.

It certainly would be easier to just buy a car with A/C. For the cost of the parts and regassing, you'd get a whole car with A/C, but it wouldn't be a datto.

Up to you, ring around wrecking yards.

Maybe the 210/b210 in the US got A/C more frequently that it's Australian brother.
