Turning bubble into butter?

I have a friend who has asked me to make her some butter from some of my trim. I've made it before with good success. The trim I have is a year old, and even though I've kept it in the dark in full sealed jars, it has broken down.

I just made my first bubble run last weekend and am waiting patiently for it to dry before I smoke it. I really enjoyed the processing so I had an idea
to do a run with my 8 bag system, and discard the wasted leaf in the 220 bag and the glands from the 190 bag and then use the glands from all the remaining bags.

My questions are:
Should I just use the 160 bag for butter?
Is this a good idea or too much effort to make butter?
Will there be a noticeable difference in the end product compared to if I were just to follow some of the butter making recipes? What I mean is will it be a cleaner buzz?

Thank you all for your input.

Kindest,
