Well - at >40oz you are up against a hard limitation, IMO. The fault, dear Brutus, is not in our stars, But in coffee baskets. Somewhere around 40+fl.oz you can't fit enough coffee into a cone that it won't make a mess *if* you have a really good water dispersion nozzle system. I am not a fan of 'basket' shaped filters (either paper or metal-screen), but they can do considerably higher volume - maybe 60+ fl.oz.
I got a 'Breville Precision' unit a few months ago, and it has a lot of nice features - like pre-wetting the grounds, controlled delay, then make at controlled temps & flow rate (slo,med,fast), high quality thermal cafe, can do pour-overs. I reviewed it briefly here somewhere, BUT after 'playing' with controls for a few weeks I settled on a temp, flow, pre-wetting time, etc close to their SCAA default, and have no need to ever tweak them again. This unit uses a heat-block&pump (yes, really) and they don't guarantee SCAA spec for the basket (maybe the water volume overwhelms their heater). I haven't used the basket enough to say how it differs.
This breville makes a great cup - as good as the 3 Bonvitas I burned up, and the moccamaster I had for a year, and can use either a cone or basket - tho' I only use cones.
My old Capresso is still on the counter top for my wifes (ugh) decafe. At the 'MAX' fill line it holds 50fl.oz, & they make great thermal carafes. If you are lucky enough to get a Capresso that happens to hit good brew temperature - then they are just fine, tho 'IMO a slight notch below the others
When comparing the two, the Breville with 68g of grounds really dirties the paper cone to near the top edge, while the capresso grounds only ride up the cone side less than an inch. The pre-wetting and better water nozzle in the Breville seems to be the difference. Breville is spec'ed at 40floz for cone & 60floz for basket, but normally overload to 42floz cone.

So .. IMO if you really want 50-60 fl.oz of great coffee, you need to consider using a basket system, despite that the flow pattern is likely to be sub-optimal. I'll suggest you consider ...
A Bunn with adjustable temps. These are so fast you may not need the capacity, or the Breville Precision.
You probably know the decent cone machines, Moccamaster, Bonvita, Oxo, Breville - then a few new SCAA tested models.
