If the edge grind on your CR Insingo is already relatively thin behind the edge, diamond or cbn rods might at least make the job manageable.
I used a similar V-crock compact 'Field Sharpener' setup from A.G. Russell with it's included diamond rods (600-grit or so), to thin the edge on my large Sebenza in S30V. Because the blade was already a pretty nicely thin grind behind the bevel shoulders, it didn't take a horrendously long time to reduce the edge angle a bit - maybe 45 minutes or so. The (round) diamond rods on my setup are pretty small too, at slightly less than 3.5" working length. Even so, the diamond did make a substantial difference as compared to trying the same job with only ceramic rods, which would take many, many hours at least.
