Trade For Kelce?

I’m currently sitting at 10-1 in my 2 QB Dynasty PPR League. Unfortunately Mark Andrews was my TE. The team who has Kelce is sitting at 4-7 and is selling. He offered me Kelce for Andrews and a late 24’ first rounder. I know it’s a lot of value to give up but with the context of the situation should I overpay here to set myself up as the championship favorite?

The best ROS TE available on waivers is Logan Thomas.

Here’s my current roster:
QB-Pat Mahomes
QB- CJ Stroud
QB- Geno Smith
RB- Tony Pollard
RB- Josh Jacobs
RB- Rachaad White
WR- Tyreek Hill
WR- Keenan Allen
WR- Adam Thielen
WR- Deebo Samuel
WR- Garrett Wilson
WR- Diontae Johnson
TE- Mark Andrews (INJ)

Thanks for the advice!
