Reggie Wayne for Willis Mcgahee Straight Up... Who Wins??

i need another RB (since henry is hurt/gonna get suspended), i know i cant replace wayne with anyone really, but i have brandon marshall to take his spot, should i do it or not? and do you think the other guy will accept? he also has addai, SJ, and bush as his other backs (amazing, dont know how he has all them). So do i propose it? and will he accept?? Thanks!
