I'd heavily suggest that you perform a very heavy and serious exercise of "what do I actually NEED" before buying more camera gear.
I've read you post (seemingly over and over) about how each camera being discussed doesn't quite fit your needs for one reason or another, and TBH it really just sounds like you're turning your nose up at anything that isn't the space shuttle.
Forums and online communities are full of things that "everyone knows" which are, to be frank, complete bullshit. The reason I do so much testing is to sort out what is true from what is "known" (but complete crap), and from my experience about a third of what I read (and subsequently test) fails miserably to be remotely true, and once you look at the results and think it through, fails to even make sense.
Your "needs" contain their fair share of these things, so I'd suggest you take every "need" you have and then test it.
It will be one of the most freeing things you can possibly do.... once you realise there were all these constraints you were putting on yourself that weren't actually needed at all the possibilities open up before you and instead of feeling frustrated and cornered, you feel that there are options and possibilities to explore.
