This is lovely, but if you didn't want to see RayV brushed aside on the show, I don't see why you had to have him brushed aside here, and Fraser with RayK instead.
The show actually said nothing about RayV marrying Stella (I assume Ray sent Fraser an invitation to his wedding to her). It only said in the epilogue that RayV and Stella went to Florida and opened a bowling alley, so you don't have to believe they married. You also don't have to believe that RayK stayed in Canada with Fraser permanently, or that they became lovers. The ending is so open that there's room for Fraser and RayV to reunite after Muldoon's capture and be together again, so if you want to write that, then do!
