Rebar inside steel tubing for additional security against cutting

I am replacing my existing home window and door security grills with thicker gauge RHS (rectangular hollow section - steel tubing) and I was wondering if rebar inside of RHS would add any meaningful reinforcement from cutting with a hacksaw?
My thinking is that, while rebar is pretty easy to cut with a hacksaw, hanging loosely inside RHS, it would just spin around and not be easy to cut.
Home invasions are a common issue where I live, with 3-4 armed burglars forcing their way into homes without occupants being aware. They predominantly use basic hand tools (hacksaw & crowbars) to cut an opening where they can gain access. I am doing a general security update, so I'll be implementing other strategies as well as putting in heavier duty security grills.
The walls are all concrete, so the weight of the structure isn't so big of a deal.

Answer:
Yes, it is a common strategy used in the manufacturing of security windows. Nothing will stop a determined burglar, but everything you do to slow them will be helpful. Keep in mind that hacksaws are a thing of the past. Today it's more likely they'll use a battery angle grinder, unless noise is a concern.
