Indeed! indeed!
Great stuff C$$ 
I remember that post of yaz--we need to dig it & add the link here--but you've summarized the stuff really nicely here 
Another great thing about the dominant chord is that it's not so "tense/ deep" as the fully diminished.
I am going to try all these suggestions..
Well fam, keep the ideas flowing 
Exactly @ "not so tense/deep". There are so many options when using dominant and/or suspended chords, that once you finally realize this, your use of the diminished will start to get a little lonely! lol Because, you have so many more additional colors to paint with (so to speak).
And it seems to me with all of this "chord study", the main goal is to have "expert chord control". Meaning: you want to get to the point where you can make the chords do ANYTHING you want them to do, or strike up any mood that you want to strike "AT WILL".
And part of mastering that is, understanding
"inversions & voicings" to the point where you can make the "lead note" sing in any way you want!
Jonathan Powell (at Jermaine Grigg's
"Hear and Play") said a
few fleeting words on that, that just open up the floodgates to my thinking!
Notice on Jonathan's
Urban Pro 600, how he stresses knowing all your "inversions", because he says the inversions will make it seem like you know a bunch of other chords, when in fact, it's the same chord, only it's "inverted". And with that knowledge, you can make your chords "sing" because the LEAD NOTE keeps changing with each inversion. THAT'S when you really begin to master & personalize your chords!
Good luck with your experimenting with the above ideas!
