Kelce Trade Value as a Flex

So Kelce is on the trade block in my league because his owner needs rb help. It’s a no-TE league so he just plays as a WR. Would it be worth paying whatever he costs if I have AB, OBJ, and TY Hilton already? I’ve basically been riding those 3 this season so kelce would just swap in and out with Hilton based on matchup.
My rbs are Ingram, Chubb, Michel, Chris Thompson, Kenyan drake and aaron jones and I would have to give up at least one of them to get Kelce.
