If I was doing this, I would simply look at the 4 staves and in a new file, create a single line part, using my experience to condense this onto one staff. I did this in 3 minutes.

(I just noticed I made a mistake in ms. 3, the HH should hit on beat 4.)

Dude, cool! Your experience is awesome!  Care to share your tips?

Just take your time and put all of the necessary information into one staff. Finale isn't smart enough to do this, but the human brain is.

Put the Bass Drum and HH foot in layer 2, the downstem notes first. Then add the snare, HH and Cr. Cyms in layer 1. The first few measures will take you the longest, but once you understand the workflow, it'll go faster.

OK, I was able to copy paste the layer 2 kick and the Layer 1 crash and snare into my score just by turning on Document->Show active layer only while pasting.

That saved a lot of time and human error possibilities. Then I started working on adding the Hat.

I noticed that Logic (using Rock Drummer track->convert to MIDI) and Finale (using Fusion Drum kit) have different notes and different sounds. 

Here is Logic:

If you look at the text to the right of the vertical  keyboard you can see Hi-Hat Open, Hi-Hat Foot Close, and Hi-Hat Closed. Finale has another option. Go to the Score manager, select the drum set line, click Settings... next to the Notation Style: Percussion pulldown in the lower right, select the Drum Set and the click the Edit... button in the lower left to see the hat options including Open and Closed are both there, but Finale has Foot and Foot Splash. And Finale has many more than that if you want to choose from the complete list:

Comparing the two hat "translations", the Logic sounds for the hat are pretty much all hat slightly open. In Finale, the translation is strange and sometimes doesn't playback the same notes in the same way! I think that is because the cases where we have both Hat Open and Hat closed together, sometimes the open comes first, sometimes, the closed comes first  somehow.

Are you using the Finale drum part for playback?

I also use Logic. When I have a Logic Audio file, I have no need for an audio file from Finale. So I don't worry about playback, I just make sure that it looks correct on paper and that everything is in the correct staff position.

Yes and no. I'm composing this piece in Finale, not in Logic. So I do use the playback from Finale. 

There seems to be multiple schools of though about notating the Hat. This exchange:

https://music.stackexchange.com/questions/54057/how-to-notate-a-quick-open-and-close-hi-hat/54059#54059

Uses the + and o above the hat to indicate closed and open, and the low x below the staff for a foot splash.

that claims to follow http://www.normanweinberg.com/uploads/8/1/6/4/81640608/940506pn_guildines_for_drumset.pdf

has pretty much the same thing. So we need Finale to support the + and o above the noteheads.

Going through in Layer 2 and first adding the Hat Foot was the easier workflow. Then, going through in Layer 1 to add the Hat, modifying the rhythms to fit in with the snare was the hardest.

Also, it is tedious to try and get the correct Hat (open vs closed) as it is the very slightest of motions with the wrist on the mouse. Ouch! NOT ERGONOMIC.

Since you have to go back and add the open circle individually, you could notate all HH's as closed and then use the (alt) arrow key to change them to open when you go back to add the circle.

I noticed you used MIDI. Logic Pro X is a DAW supports MusicXML import/export. Would that have saved some steps?
