Have you looked at what's available on a Wrangler lately and what the price tag is? The market is there for the taking. There is just no effort for taking.
It's an interesting question as to where the price point should be. Right now, Land Rover has two vehicles that will hover between $40,000 and $45,000 when equipped decently; the Discovery sport and the Evoque. The step up to the LR4 is a big one.
That said, people are more than happy nowadays to spend $45,000 on a pickup truck they don't actually need, a utility vehicle, or even just an off-pavement toy. Off the rack, you'll end up just shy of $40,000 for a Jeep Wrangler if you want a well equipped model that promotes the lifestyle.
If we were to position the Defender as I suggested in my initial post here, that price would be possible, but Land Rover's cheaper platforms wouldn't. They won't underpin a "Defender".
It would need either a new or borrowed ladder frame, or the LR4 platform, which may leave it with a fixed wheelbase.
The cost-cutting to bring it into financial reason would be possible, but you're ending up with independent suspension on their own platforms. Even so, they've done well with that these days. It could be a differentiating factor.
Of course, there's nothing saying Land Rover couldn't partner with another manufacturer for a traditional platform. It's been done many times before, and now quite a few of those are manufactured here. It also wouldn't be the first time Land Rover has done it.
There are a lot of interesting possibilities. They likely won't be explored, but it's fun to think about.
