The Aerowind may have an ovalized seat tube. I've never examined one, so dunno for sure.
If so, replacing the FD with something lighter/more modern may not be easy.
Also, at least some Aerowinds were originally equipped with Shimano's Adamas AX components. Velobase appears to indicate that at least some (maybe all) Adamas AX cranksets used a FFS and/or Selectra-type bottom bracket. I believe those require a special tool to remove.
Just pointing out possible complicating factors associated with using the Aerowind frame as a basis. The Santa Fe could prove far less painful if used as the base frame.
IMO seeing either decked out in modern CF components and coming in well under 25lbs would be a hoot.
