I'm assuming you have a Tekwing with the ABS backplate, and twins, so please correct me if I'm wrong. I guess it's all about lift, and whether 22.5 KGs is sufficient for twins + stages.
Adding a s/s backplate may help as long as you have sufficient d-rings to hold the stages. I suspect you could use the Tekwing's side d-rings and then simpy ensure you have d-rings in the correct place on your harness to allow you to carry these comfortably, but as I said, you might want to check the Tekwing's 22.5 KGs is sufficient.
