Support roof beams against existing wall

As I mentioned in my renovation thread - https://www.byggahus.se/forum/threads/terom-renoverar-och-star-i.283451/page-2#post-2583242 - I have a horizontal 120 stud that supports the beams of the garage roof. That stud is nailed to the wall studs against the house and is in the way. I was able to remove part of it when I opened up for a sliding door, but now I'm looking at whether I can remove the rest as well. I can't insert a stud sideways from the inside, but I can from underneath. So, the idea is whether it's possible to insert a 145 stud into the standing house wall studs and place, fix with angle brackets/nail plates, a 200 beam piece on this that the garage roof beams, about 3 of them, can be attached to with joist hangers instead. How would this affect the strength of the house's exterior wall? That wall supports the intermediate floor at one end and the exterior wall for the upper floor but not any load from the roof trusses since they run in the same direction as the wall, perpendicular to the intermediate floor. In the schematic below, the "house" is at the back and the garage at the front of the image. The beam closest shows the current principle, and the other section shows how I might be able to proceed. Any comments from those of you who know about house construction?
