I just re-read your post....
You need a larger or 2nd sump
You can cascade as many tanks into each other as you want as long as the sump/s can handle all of the water when the power goes out

My largest set up were 7 all flowing to a common sump. 4 tanks directly to the sump, the other 3 cascaded into each other and then flowed into one of the larger tanks...to the sump
Another sump would also work, but I would drill/plumb the 2 sumps together.
2 or more separate sumps leaves you 2+ to worry about running out of water instead of one
Keeping the number of pumps down to a min would also help
Time for a bigger house

Then maybe the van could fit inside the new garage
