Premiere Pro :: Turn Off Time Remapping - Original Clip Gets Grey Stripes Over It?

I'm trying to apply the time remapping settings from my original clips to those that I've colored in DaVinci Resolve. I turned off all effects on my colored clips and graded the entire clip, not just the segment in my original timeline.  My workflow thus far has been this:
 
1) Copy the original clip above the colored clip

2) Revert the speed of the original clip to 100 from where it was adjusted to (the speed of the original clips varies from 500% to 1000% across the timeline)

3) Turn off Time Remapping on the original clips (this is done by deleting all keyframes)

4) Find the In and Out points of the original clip through timecode

5) Set the In and Out points of the colored clip to those of the original

6) Make another copy of the original clip and set it to 100 but don't turn off time remapping

7) Copy the time remapping settings of the original clip to the colored clip

8) Convert the colored clip to the original clip's speed (usually between 500% and 1000%)
 
Now, in several cases this works, but in others it falls apart at Step 3.  When we turn off time remapping, the original clip gets grey stripes over it in the timeline and we cannot see the footage in the Program or Source viewing monitors.  We have tried reversing steps 2 and 3, but when we do that the clip gets shrunk down to 1 frame and we lose the original In and Out points.
