And, that's great--on sources. Also, no you aren't boring me in the least. Don't let my being adversarial put you off either, that's just how I often am, and my intent is to both learn from your answers as well as push you out of your comfort zone.
But being the industrial engineer / production planner, what I still see is engines being a huge bottleneck in getting the 262 operational in anything other than miniscule numbers.
Even if the engines can be rebuilt, taking roughly a day to do so (more realistically it's probably several), the Luftwaffe faces several issues in that respect. If I recall correctly, Luftwaffe ground crews and maintenance workers got little, if any, specialized training in maintaining jet aircraft. This really isn't unusual in any organization where the management and leadership are not engineers and have had some experience and training in what maintenance really takes to get it right.
That's a lifetime of personal experience in that. Maintenance is often an afterthought, and only gets pushed to the front of the line when things stop working.
Anyway, if the engine needs an overhaul, you need the various parts involved in doing that. That means either you are making way more parts than are being used in making new engines, or the rebuilders are competing for existing parts putting a crimp on new engines. If the rebuilders are using some engines for parts to get others running then that's just a recipe for trouble.
Of course, there's the fuel thing too. An Me 262 consumed somewhere between double and triple the fuel of an Me 109 per mission. Even if it was easier to make jet fuel, the total needed was vastly more than German industry could provide and the transportation system could deliver.
As for the Me 163, the Bachem Natter makes more sense as a rocket plane. The Natter is for all intents, a manned SAM using the pilot as a substitute for a terminal guidance system and VT fuze. The Natter launched vertically, was guided by an autopilot to within intercept range of the target where the pilot took over and made the final approach an attack.
After that, there was an attempt to recover the engine and pilot as these were too valuable to lose each mission. Costing far less than an Me 163, the Natter system could be made semi-mobile and set up like SAM batteries to take on enemy bombers.
