Not being a chemical engineer, I'm afraid I can't really answer that. However, from the little I know, I'm not quite understanding why you'd actually want to do that for cycling purposes.
Krytox grease does exist in a variety of viscosities suiting an equal number of applications. Depending on load, revs, exposure to contaminants and what have you.
Also, can Krytox be used with ceramic bearings w/o any issues arising?
From my perspective there's little use for a hybrid ceramic bearing unless you lube it with Krytox grease (which is what the guys at Ceramic Speed do) or be more adventurous and use oil. (Krytox oaded oil, that is)
One proviso for the latter is that you may need an arguably deeper pocket in that it may not last that long, it obviuosly will need more frequent relubing too.
There really is no industrial bearing that is factually nor actually designed and lubed correctly for cycling use. They are all designed with heavy loads and high revs in mind.
As an engineering consultant CEO we used to say "ce qui peut le plus peut le moins" , which boils to let's overdesign the thing so we'll know it will work and last.
In cycling you need to put that compromise in a different perspective. You want the best possible performance at really low revs, low load and low friction. None of these bearings are designed with that in mind and as counterinuitive as it it may seem what could do more than what it was designed for is now actually dragging you down.
The ideal type of bearing for cycling purposes is (a few exceptions notwithstanding) the cup and cone bearing. It was what has been used and choosen years ago by engineers and still is to this day the best choice overall from an engineering POV as well as a performance POV.
That's my POV from an ideal world's perspective anyway.
