So far I have made one ceramic wick, for my RSST. Unfortunately I did not have a diamond coated blade for the rotary tool, but I had a large stack of standard cut-off wheels, and after going through perhaps 8 of those I had my wick shaped. It was slightly larger than my RSST's insulated wick opening, so I removed the insulation and it fit nicely. Wrapped a 3/4 coil around it and tried it out for a couple of days on the Vamo.
While it worked, it was not as good as my cotton wicked Protanks. So I thought that perhaps it needed a little help getting more juice up the wick, and I pulled the coil off and started again, this time wrapping 2 strands of Peaches and Creme yarn (half a yarn string) around the ceramic from the bottom spiraling up to the top, and wrapping the coil around it. That produced much better vapor and it seems to keep the ceramic much more lubricated.
While still an experiment in progress it does seem promising and gives me something to play around with while I am at home. When I am out and at work I still carry the mech mods and Protanks rather than the RSST (leaks if not kept upright, no fill hole stopper, etc) but I think eventually I may get the RSST to the point that it might one day become my preferred vape at home rather than a Protank. Maybe. It does have going for it the fact that the wick would need to be replaced FAR less often, but it is not really conducive for a daily carry/travel rig.
