The string of CoS's that followed him were the result of no one being able to properly fill his shoes. No one could work with Goering and/or Milch so were kicked out. The post-Jeschonnek (who survived for 4 years in that role) CoS's in the Luftwaffe all gained experience and prominence during the war, so weren't an option during the pre-war. Both Milch and Goering liked Wever, had a good working relationship with him (and the go between sometimes), and he had Hitler's ear. I cannot speak for what wartime would bring, but given that Jeschonnek survived in this role until 1943, I don't see why he would be kicked out any sooner, especially given that Jeschonnek had far worse people skills and had many more enemies than Wever. In fact I cannot name any powerful enemies that Wever had at the time of his death.
You are ready history backwards too, thinking that the same issues would creep up ITTL as IOTL that resulting in powerful people being removed. The LW was a different beast than the army, especially as Hitler didn't have the same direct, sustained contact he had with army officers. Wever was also a pretty outspoken Nazi and wasn't out of step with Hitler's foreign policy the same way Blomberg was. Perhaps something would happen to him as the result of a reaction at the Hossbach conference like it did with Blomberg, but Blomberg's fall was the result of specific circumstances that wouldn't apply to Wever. During wartime perhaps he can have a shouting match with Hitler as Guderian did, but that would be very out of line with his OTL behavior.
As to Milch sticking around, so long as the war is on Milch is safe in his position. He quickly proved himself capable in his job, so it would be politically dangerous to touch him before 1945. So Wever has no reason to be removed pre-war, baring something bizarre, which keeps Milch around until the war, during which he cannot be removed unless something equally bizarre happens, like IOTL when Milch tried to get Goering fired in 1944 and was instead toppled.
I was talking about COS throughout the entire wehrmacht, not just in the LW... when reverses happened or they criticized just too much, they got tossed. Wever in the long term (especially under war pressure) would have a hard time tolerating Milch's empire building and Goering's not taking the conflict seriously. Wever was a devout Nazi, but he wasn't a yes man, and non yes men got tossed once the shooting started (Guderian is the relevant example... and Wever would go before him because the LW experienced reverses earlier than the Heer)
Assuming Wever didn't build up enemies in the remaining prewar period (Milch is the obvious one as Wever wouldn't stand for all of his empire building and would get really pissed at him eventually), wartime would bring them as conflicts with combat commanders would grow frustrated with the LW's beauracracy and or think themselves better fit's for COS than Wever; Wever's counter responses to them with quotes from Mein Kempf are not going to improve things and he will eventually have to go, assuming the LW's first failures or high losses in the battle of britain (which are inevitable) don't lead to him getting housecleaned anyway
BTW as discussed, his support for the bomber A project was ultimately a really dumb idea and if played out with his living, would have been a dumb idea in practice
giving contracts to Heinkel for anything was among Germany's dumbest arms decisions
