I've never seen an Abutilon that big, but i've only seen a couple and all in containers. One was about 5ish feet though! And in a tall container it was towering! The folks had it in their entryway in Northern California so it was pretty protected from frost. My mom had one in WA and didn't bring it in for the winter and it did die. Common names (what I searched was the Koelreuteria bipinnata aka- chinese lantern tree) can be pretty misleading. I don't think the Abutilon will get that big but wow that would be so epic! Maybe you can find the giant one (koelreuteria) somewhere !
