I guess the answer is no. I tried it, seemed very "shreddy" (not dense, just not like a marmalade to me). So I tried Ellie Topp's version with only 1C of squash instead of 5, still a lot of pulp/shreds. So I mixed that in (before adding sugar) to the Ball version and stuck it in the fridge while I made a "jelly" with a quart of bottled lemon juice, the rinds and ginger that I'd already boiled in the squash mixtures, and 4C of sugar. Poured out half the lemon juice/sugar mixture, added half the squash/citrus mixture and another cup of sugar b/c it didn't seem sweet enough, brought to a boil then added half a packet of (expired) liquid pectin just b/c I had all that lemon juice and didn't know if I'd get a good set. So I made 2 batches using 1 packet of pectin. And it set hard! Looks nice, got a bit more of the marmalade look I wanted, still quite a bit of shredded squash. Still tastes a bit like squash and not too much citrus though. And definitely needs more ginger, though I did add chopped crystallized ginger to each batch after combining with the lemon juice.

So IMHO, both the Ball and Small Batch recipes use too much pulp/squash. I think next time (if I ever make this with summer squash again) I'll just go with the lemon juice and pectin (or lemon rind) to get a clearer marmalade like the Quick Lemon Ginger Marmalade we like from Ball, or try Linda Z's Lemon Ginger Marmalade which doesn't use pectin but calls for straining the lemon pulp/juice through a jelly bag, then add lemon zest and shredded squash.

But I think there are probably better things to do with excess squash - I'll probably just make plain Lemon Ginger Marmalade from now on. And put it on the zucchini bread!

Thanks for posting your results. I don't grow zucchini myself, but am often offered some by those who do. Think I'll take a page from your book and just make the zucchini bread!

For a different take on zucchini bread, try Martha Stewart's zucchini Parmesan bread. It's a savory quick bread. Freezes well. Super yummy as a base for a tomato sandwich.
