yes, most certainly.
just check out KEF Blade and you'll see how they've done it

Acoustic Research did it with the AR9 in like 1978. Physics hasn't changed since then.
Why 4 x 6"? Go with a couple of 12".
Yes. What are your design goals? You must have something in mind to have selected the driver sizes already.
I spent time with AR-9s (dual 12s per speaker) and now I have some resto-modded AR-90 (dual 10s per speaker)…the kick on both of these outshine most anything produced even today. 6” seem like a waste, consider side fire, magnet coupled push-push 10”, I think this might be the sweet spot
I think over it but now I have 8 no of 8 ohm 6" sub for size and impedance matching series and parallel total 8 ohm
Fair enough. I often do projects with what I have on hand rather than what I could use. Mount them as close to the floor as possible to get the most out of the Allison Effect., basically making them radiate into half space for some small increase in LF efficiency.
Please post a design and build thread as there's a lot of expertise available here, and many just like to watch other people's projects.
I'm finally going to build my C21 version of the AR9 next year.
Pictured is the, AR-9, mentioned above. Introduced in the late 70’s

Dual 12-inch side-firing acoustic suspension woofers. These were big speakers.

Brett, just in passing, I‘ve imagined a remake of the AR9 utilizing Morel’s TM-4055-8 dual dome tweeter/midrange array in place of the original AR9’s widely spaced domes.

Be interesting to see what you come up with using that Morel dual dome. Not my cup of tea, and for myself I was speaking of general format, rather than a specific clone. I have a bunch of drivers in mind, or on hand, and am approaching it from a 'how would I build a similar format speaker with today's technology and drivers?'.
It does when you have to pay for it in a country where walnut is not native and you build larger speakers.
I do like it though.
Regarding OP I wouldn't embark in such a project... From a diyer POV a modular design would be more effective.
And lately(in the last ten years I mean...) I keep woofers well away from ceilings and floors

Why you ask that? If you like the emission integrated with the surfaces around, go with woofers attached to the floor. If you don't like it, find out how to minimize the issue. The baffle itself...
Because I'm curious.
The driver centre to the floor is a small fraction of a wavelength in it's bandpass, so I'm curious how you're determining that it's somehow deleterious.
because the speaker is not just another piece of furniture, but is the terminal of that system that reproduces music.
And gravity plays a role, as heavy pieces of furniture are put on the floor.

you know the +3dB of halving radiation space, so that's the unwanted effect to be avoided.
