So… it sounds like you have created the world’s largest linear turret press. ;-)
(I use an RCBS4 in line with my compact turret press. Sometimes you just need that extra “umph” to resize.)

I do something similar. The weakness of a turret or progressive is if you clean out your primer pockets - decapping is a single stage operation. I prefer to expand the case mouth before seating a primer, so that is sometimes a single stage operation. Then how well does your press handle priming? When I first got my T7, primers would not seat below flush. The turret is loosening up now, so on-press priming is getting more effective. There are times when the turret is just to seat & crimp as a 2-stage operation, and everything else is single stage.

On the other hand, when using virgin brass, and if the primers seat with the on-press priming feature… I can do everything from sizing the case to final crimp on the turret. That’s a good day.
I have about 20 presses but not a lot of room in my gun room. I have only two presses set up a Dillon 550b and a Bonanza CO-AX. The 550 has dedicated die plates for my popular pistol rounds and the CO-AX changes so fast there isn't much reason to line up three presses. If I wanted to fully load each round for limited runs of ammo, I would set up my Lyman AA. However I usually batch size, prime, charge and seat cases.
I load all my rifle ammo on multiple single stage presses. Since all my brass is completely prepped and hand primed all I do is powder drop on the first press, seat bullet on the second press, then crimp on a third press. I am thinking about setting up my 550 for .223 though.
I had a two station similar to that, I got it from my uncle along with a rifle when he stopped shooting competitively. That one was only two stage. Loaded a lot of ammo on that one. Zero issues with it. Set up the dies and start loading. Had a powder dispenser and scale beside it on a shelf above. Loaded a lot of ammo on that set up!
