FWIW, the trackhawk is a few seconds faster (but probably double the money)
Trackhawk is a Grand Cherokee, which means unibody and independent suspension all around. Those are quite well sorted, and the chassis can more-or-less handle the power.
That much power plus solid axles front and rear in a Wrangler/Gladiator ... ??? ... I sure hope someone in the chassis department has put some effort into this.
I predict the presence of a top-speed governor to keep it within bounds of what the tires and suspension and brakes can handle. Might not actually be capable of going any faster than a V6 Wrangler/Gladiator ... tire speed limited, and stability limited.
The cooling system is a towing-capacity-limiting factor on the Wrangler/Gladiator. The hemi engine isn't going to help matters. It'll be interesting to see how they deal with this.
