Not sure if tour would ever consider a half cage for a street car, with the objective of making the chassis more rigid?

This is up for debate, but most bolt-in roll bars for this chassis will absolutely do nothing to increase rigidity. They tend to bolt down to weak parts of the car, and don't have a very tight fit because they accommodate for the trim/headliner.
As for a half cage that is tied to structural members of the car (and not just the same as a bolt-in that got welded in), then, no, still no. For it to make a difference, the cage needs to reach both ends of the car. A half cage will just brace the back to the middle, which does more to add weight than it does to tighten up the flex between the front and rear shock towers.

The main gripe I have about "street" cars having full cages is that it's unsafe for the occupants who aren't wearing helmets. Which in a street car, will be 99% of the time. If the car gets hit on the street or the guy drives over a canyon, he's at risk of hitting his head on the bars above him due to the elongation of the neck and potential looseness of the stock seat belt. The point of the helmet is to cushion the blow when, not if, you get hit. The purpose of getting a cage installed in a car is because you acknowledge the reality that you will get into trouble; it's only a matter of when. So a helmet is always paired with that stipulation.

Long story short, a cage is designed to protect the car from cumbling in on itself. It is not designed to cushion the fleshbag inside of it. The fleshbag must be secured inside the car with the right equipment, or the cage itself will pose its own danger to the fleshbag.
