Many of the HiFi speakers had taller feet/stand offs to get a little more clearance if they had downward facing woofers or ports or the base of the speaker was part of the porting.

Downward facing ports have acoustic loading that depends on the distance from port to the adjacent surface. Changing this distance can alter the response, it’s not a random guess.
Yes, it depends on the design, as acoustically, the floor actually becomes a part of the port, unless there is a shelf between the port and the bottom of the speaker (as is the case with my 225's - there's like a quarter of an inch gap all the way around the speaker bottom, between the port exit and the shelf).
Here's a link to a pic of the 225's.
Re #2; your problem with this one is the head sliding off the cab.
There's no particular reason the head has to be placed on top of the cab.
Can’t you set the head on something by the can or even at your side and tip the can back. The head doesn’t have to be on top does it?
Nice. I arrived at a similar, though different approach just recently: Here I have the Avatar SB126 (1x12, 1x6) sitting on top of what looks like a plain black box, which is actually a de-badged GK MBP112 powered cab. Lifts the Avatar up to a nice height, gets it off the floor (it's a very deep sounding cab to begin with) and if I need the extra ooomph, I can turn on the MBP (the MB200 head can run both cabs simultaneously). Have not gigged it yet, but the cabs do sound good together in a rehearsal room--we will see how it is out in the wild. Chances are I'll rarely if ever need to turn the bottom cab on anyway. I just stuck some velcro on the head and on the cab--I can always peel that off-no biggee. Don't want the "micro head dance" to happenI use a Fender Rumble 100 combo and prior to that used my own designed 110/6 cabs with a lightweight separate head.
I recently just made my own cart/dolly/stand for the Rumble. It's more useful/versatile for a stand as it also carries everything I need in the lower "milk crate" storage area that I can wheel from the car to the stage. It also has a collapsible handle on the back so I can tilt it, and use it more like a dolly than cart. Rather than carrying a separate stand, the cart becomes the stand.
Oh...and the rubber feet on the bottom of the combo fit perfectly snug in each of the four corners of the lip of the milk crate storage area.
Coupling a cab to a floor for some kind of acoustic effect isn't all it's cracked up to be anyway. If you're playing on any concrete/tile, etc. floor it makes absolutely no difference. On hollow/raised stages it just makes it a noisy low end mess of things without much positive result sonically anyway.
