Damn good plan. I'd for sure try to lure Kirk there for an immediate remedy at QB and that may entice Evans to join him.
Already having Rhamondre Stevenson at RB, I'd go with the cheaper option of Ekeler rather than Saquon, then draft Marvin Harrison Jr or Drake Maye, if you believe in his talent. Perfect position for him to sit and learn behind Cousins for a year or 2.
Your offense is now set and one of the best in the league on paper.
