swappng and converting headlight housing and front end

I had an idea to basically convert my front end to a ranger / pathfinder using 1999 2006 headlights from a ranger and cutting or eliminating my chrome front end replacing it with a billet grill from a ranger and wrapping the lower portion with a Nissan 1999 bumper because i believe the specs from nissan says proportinatly it will fit . How much of a btch can it be compared to what i have done so far what do you guys think?

guess it boils down to some cutting of the core support for the lights
and welding in new headlight buckets. then making some brackets for the bumper, not too bad.
