This guy took his 0 degree bag and added this $50, 8 oz SOL bivy to it and it kept him warm enough at -3C that he had to take his clothes off.

Bivy in question
I can think of two options you might not have considered:
A) basically a space blanket
B) synthetic insulation from recycled plastics like [here] (https://www.rei.com/product/112623/big-agnes-encampment-15-sleeping-bag)
I think most of the suggestions you're getting are actually quilt alternatives that you could comfortably use instead of a sleeping bag even at 0C/32F (and colder).
​
For nights where you're confident you'll be experiencing lows of 10C/50F or higher, you can get by with a very minimal, summer weight quilt that weighs 10 or 12 ounces. They aren't that cheap, though, for an item that may be used only rarely.
​
Another alternative for those warmer nights is to use a SOL Escape Bivy, which uses an aluminized tyvek material and weighs around 8 ounces, costs $50 but you can find it for less. The SOL Escape Bivy wasn't really made as a sleeping bag alternative, but it breathes well and many people have used it as sleeping bag alternative in warmer conditions. Not toasty warm at 10C/50F, but okay if you're wearing clothes. You'd want the SOL "Escape Bivvy", not the "Escape Lite Bivvy". This one is green, but they also come in orange: https://www.amazon.com/L-Survive-Outdoors-Longer-Water-Resistant/dp/B00EZEPCB4?th=1
The SOL Escape Bivy is relatively inexpensive and pretty durable. Couple with a Therm-A-Rest Z-pad and sleeping bag and it should be pretty comfortable.
