As the title states, I would like to saw up this door opening to accommodate a taller door. The door opening is currently about 196cm in height, I would like to fit a 21-frame.
Doorway in lightweight concrete wall partially knocked out for remodeling, with vacuum cleaner on the floor and small rubble pieces scattered around.
The wall consists of lightweight concrete. How do the beams usually look, how high are they, and how much reinforcement is there in them? I chipped away a bit of the stone and can see that there is, of course, reinforcing steel.

Is it possible to saw out 14 cm to get the height I want? What measures do I need to take, such as installing new reinforcing steel when I've sawed?
 
Assuming it's a 7 cm ytong interior wall that isn't load-bearing? In that case, you can easily take the tiger and make the hole as you want it without any other measures.
 
I was considering making a higher door as well, but I'm unsure if it can be done without having to cut away load-bearing parts.
The wall in question is an exterior wall, even though there's a small vestibule behind it. The door is currently ~185cm, so I hit my head on the frame if I'm not careful.

Previous owners have covered ugly building beams with panels... If you're wondering what's there.
