Extracting and winterizing while skipping the butane

Not really. Probably pass OR standards.

There are at least a couple of discussions on the subject around here.

You will loose some terps. A (likely) unsolvable problem with ethanol extraction (keep them terps!)

With a cold trap, you’ll also get terpshine. Which I suggest you keep separate from your bulk recovered solvent.

Once you get around to ethanol recovery (also extensively covered).
