Having built a few sumps, keep it separate.
Make the sump functional, and smaller if needed to leave room for the extra mixing container.

Good recommendation, this is what I think would be best. It would also allow for future expansion or modification if needed.
Something like the 40 gallon mixing/settling tank Darryl used? Good idea. Looked like it would make water changes a breeze. Drain, fill, mix, reopen valve.
exactly my same thought. His water change system was brilliant and I would like to emulate
That's the route I am going I much prefer using a settling area over socks or other physical filtration and making cleaning the settling area automatic with a WC seemed like a great time and effort saver...
On the subject of Darryl's system... The low flow vs high flow sumpb is always an argument that interested me. I am going huge with my new sump and not increasing flow to increase processing/dwell time in the sump. Even though Darryl was not a fuge guy he also was in the slow flow category (around 500gph).
I'd love to hear your thinking on why you are aiming for a high flow through system.
I'm thinking low flow as well. There is really no benefit for a high flow sump. During my wet test, I had my DC pump dialled in about half power and things seemed perfect. My 1 inch full siphon was pinched off at about 50% so the flow was probably between 500-800 gph. I would like to keep it there if possible
In my sump i turned the refugium into a water changing area of sorts. I let the detritus settle into the fugue and skimmer sections, and periodically I would pump the water out and shop vac out both sections, obviously less often in the skimmer section. It is a great way of doing it over filter socks, etc. echoing what Rob said.
I think it is a good idea and there must be a way to get this done under your tank - gravity will do all the work. I'm not sure how you'll be able to do it all with one pump though, trying to visualize that and it isn't coming to me? Even with the method Phil proposed. Darryl's mixing tank was elevated and in a fish room, which made doing such changes a lot easier in terms of draining, refilling and mixing... I guess you could elevate a separate tank under your sump, plumb it inline, and then have it drain through a valve at the base to a disposal container or hose to a drain... and then have a split from any RO/DI line you have for top up to the change tank and mix it directly in there... you're not going to have a ton of vertical space to work with, but should have lots of run, could work very well in theory.
I have about 32 inches of vertical space under my stand so my choices would be limited. I might be able to squeeze an elevated 40 breeder under there, but still need to figure out how to drain it into the main sump. Maybe I could design another overflow, but I don't want anything too complicated adding noise and bubbles etc.
I want to keep things as simple as possible. If I have to add another pump, maybe an MJ1200 would suffice just for the water change and could also function as a mixing pump?
I can easily pump NSW into the sump by other means, but want to keep things EZ-PZ lemon squeezy if I can
