Aerial rig in house

Hi there

I am not an engineer but looking for advice please. We live in a 1950s council house in Lincolnshire, and we're looking at mounting an aerial rig in our front room for our 8 year old daughter. She currently weighs approx. 26kg and will be doing aerial hoop and silks (like in this video https://www.youtube.com/watch?v=rsm3YNWAs9k)

Our proposed solution is to put a 2630mm, 42.4mm galvanised steel tube wall-to-wall, secured with M6x75 concrete bolts, as shown in the image below. The blue wall is a supporting interior brick wall. My main concern is the other side, where the bay window is. My understanding is that this is steel reinforced concrete lintel. I am concerned that these are obviously designed to hold a static load, however obviously the aerial rig will have a lot of movement, and I am wondering whether it will be suitable to mount the steel bar in the brickwork above, or if we risk damaging the structural integrity of our house?

Thanks you in advance
