Shimano reel grips interchangable to other brands?

[Micro]

Does anyone know if Shimano reel grips, like the ones on the Curado D, are interchangable to other brands? I love the fat, soft, no-slip feel of these grips. The hard rubber grips on my Revos don't compare. And I don't want to use those slip-on rubber grip covers.  I fished in 51 degree water yesterday and in cold water you really appreciate decent grips.

I have Curado 200's and 100 D's. I like the size of the grips on the 200's. The 100's are smaller. I use those slip on grips the 100's and love them.

Compatibility may be possible, availability is a simple NO, Shimano doesn 't sell the knobs separately from the handle assembly.
