you will have heating issues. pick up a good set of scratchers. all the cooling on the trail happens in the last foot of the cooler. which is now not there.

Yes, we saw cooling issues with less extension than that...I would get a 163 cooler as well, or maybe just start with a 163 sled and save a lot of work and $$.
