Solution - scrap Disney Blade and do Blade IV
Blade IV (actually called that too not 'Blade:Resurrection' or whatever) starring Wesley Snipes, (cameos from Ryan Reynolds & Jessica Biel)
End credits scene - SLJ as Nick Fury.. "I'm here to talk about secret wars" (which would be kept ultra secret, even press screenings wouldn't have the scene, so everyone would just think B4 would be unconnected to MCU until its released)
