Leaf blowers are very overrated, unless you buy the industrial grade backpack type. And that's only a niche application.
I use a rake, which works faster for my consumer-level yard than a mid to high-range blower, to get the leaves all in once place. Then, I use the blower in reverse to chop the leaves for compost. Not the intended purpose at all, but it works for me.
You can also drop the leaves into a large trash can and use a string trimmer lowered into the can to chop them as finely as you like. Works just like a giant immersion blender, plus it's cool to take a huge pile and reduce it down to almost nothing.
If you want to avoid purchasing a blower altogether, especially one with reversible operation (1), a bagged lawnmower works equally well. I have a SunJoe electric bagged mower and I just place it on top of the leaf pile and let it hoover up the leaves into its bag.
1: As I read your post more, it seems that your blower does not officially have a reverse - you just rig it that way. That is pretty cool though any bit of debris in the leaf pile might break up the impeller if the latter is plastic.
