A business reason JW should not be the asthetic cover of any enhancements is it does not sell as well. JP is cross generational, we don't know how the bandwagon nostalgia of JW will last and frankly, it does not sell as much.
I can walk into a walmart, target, Kohls and find more Jurassic Park T-shirts and apparel than I would JW. There are spurts as the new movie is released for toys like for the first JW but even at Universal you still see Jurassic Park selling more merch.
Isla Adventura is the original park opening in the world of JP films anyway. Not that anyone notices that anymore.
