I am pretty sure they will have something to offer. It is their new business model. Wouldnt be surprised if they are working on it right now. They usually get prototype vehicles direct from Ford prior to the actual release. Good for the "Shelby Faithful" but the questionable value to the purchaser. Most of the modifications you would see would be similar to what you see with the F150 Raptor. "Branded" aftermarket bolt-on parts. Lift kits, wheels, tires, bumpers, winches, interior, and exterior carbon pieces. They have a close relationship with Borla so the exhaust would be something you would probably see. You would probably see striping packages, badges, interior leather upgrades, and the like. WIth performance, you may see intercooler, Cold AIr Kits, and probably after the aftermarket has them turbo upgrades.
Pricing would be the determination in the purchase. If you take the Raptor price point for example you see about a 50% increase in pricing and then add dealer adjusted market value on top of that. With the price of a fully-loaded 4dr lux pkg hovering at $60K, you're looking at an $80-$100K vehicle.
