Building off an existing platform makes some sense, but modern SUVs are a set of design trade offs that probably aren't great for much other than their target market: suburban homes doing school runs, work commutes and occasional grocery runs on good roads, while maintaining occasional use functionality to pick up heavier/bulkier objects.

They don't make much sense as a commercial vehicle designed to get in and out of all day and load and unload. So your car manufacture would make a bunch of modifications, and at that point you are right back where you started.

Now if you were suggesting buy a bunch of whatever some other country had developed for the same purpose, you might be onto something.
