Twisted Piercings

I would like to learn how to modify standard body piercing jewelry (captive bead rings, barbells, etc.) so that the removable component (such as the captive or threaded bead) can no longer be removed, resulting in permanently-installed rings and barbells. The idea of permanent earrings is mentioned on Wikipedia:

There is a similar example of permanent piercings being used for chastity on the BME Encyclopedia:

I would like to know if there are any manufacturers of non-removable piercing jewelry or what methods would be most effective in converting standard jewelry without negatively affecting the piercing or the look of the jewelry itself.

While other body modifications such as transdermal implants tend to be harder to remove than standard piercings, I would like to know of ways that body piercing modifications can be made to be as permanent as tattoos.
Part of my question about this is whether or not superglue would be suitable for this purpose. For example, would the dried glue be visible on the jewelry or cause irritation to the piercing if it came in contact with the skin? I have read a few similar discussions on Usenet and on Web forums dated several years ago where superglue was mentioned, but the idea was frowned upon by some users who felt that superglue would not be the best thing to use on body jewelry.

I would like to know why superglue would be appropriate or why not, and if another type of adhesive would work better.
