Marcos, if the Ranger Ext. cab is anything like the Frontier that we deal with daily at Nissan, the windows are different per application.
The Ranger windows with the seal are only on the Extened cab, but not the Supercab. On the other hand, only the Supercab has the recessed windows with the factory tint.
These differences are due to the different structures of the two types of doors. Supercab doors and windows are designed to take more abuse, therefor the reinforcements are stronger on these doors.
The extended cab windows are on a stationary platform, so they are simply sealed on.
Answering your question, I don't think the windows can be traded due to the differences in the door structure. The 4-door windows are glued on, but have fun getting them off. :)
Why don't you want tint on those windows??
