Replacing 04 front end with 03 front end

so basically what happened is i smashed the front end of my 04 lancer es all up. as in the hood, fenders, grill headlights, the whole deal. its a write off unless i do the work and repairs myself. i have found an 03 lancer rallyart with a blown engine in saskatchewan (4 or 5 hours away) for 1200 bucks. ive talked to alot of people and the answers are pretty much torn on wether or not it would work. i understand that everything is slightly different from 03 to 04 but wouldnt it work if i changed everything?? help is much appreciated!!!!!
also i understand it will be alot of work, im a decent half ass mechanic, and if i get the parts new its not worth it
