square to round eye nose swap

[Puglia10]

Been looking for a c10 and I find a lot more 81-87's with the sharper noses and fenders than I find 73-80. I prefer 73-80.
If I bought a 81-87, how difficult is the nose swap?

I know you'd have to swap the obvious stuff - fenders, hood, grill, headlights....
But is it more involved in that? Radiator support, wiper cowls, etc? Is it worth the effort or just wait to find what I'm looking for?

Thanks!
