Hobie 18 mast and sails onto a g cat 5.7

Recently purchased an older g cat 5.7 with the rental mast and sail configuration. Love it for adventure sailing and taking non sailing friends out on the water. Started looking into new sails since it seems to have the originals still on it. By the time i have them made and shipped here to Canada I'm looking at least $1500. I can purchase older hobie 18's complete boats w trailer for that price here. My question is could I purchase an older hobie w good sails and move the entire mast boom and sails onto the g cat. Of course there would be some retrofitting. But is the hassle worth the effort.
