Maybe my answer is a bit late or you - however my wife and myself fitted pigsear/wallfix handrails to a simiiar wall.
We purchased a strong broom handle!
We marked the plasterboard where the fixing screws had to be positioned.
Next we used a hole cutter - say 28mm to cut a neat hole in the plasterboard and mark the centre of the concrete wall behind.
Then we measured the distance from the concrete wall to the room side of the plasterboard.
Next we cut a section of broom handle to the same length, and drilled a hole through the centre large enough to take a size 12 woodscrew.
A masonary drill was used to provide the hole for a good quality rawlplug.
As you no doubt have worked out - the broom handle spacer was inserted in the hole and a good fixing was made.
This worked for us as the spacer was only about 30mm. However a wider hole could have been cut and a wider spacer used for greater distances
