Puzzled - was this intended to be a question, or was there some other purpose?
Roller ball pens use water-based liquid ink similar to fountain pens, unlike ball point pens that use an oil-based, grease-like ink. In most cases, however, roller ball ink is supplied in refills that include both the ink supply and the nib and ball unit. When the ink supply is depleted, the entire refill is replaced including the nib and ball. Because the ink used in roller balls is a water-based liquid, it can easily evaporate so roller ball pens are always supplied with a cap that must be used to close the pen when it is not being used for writing.
There are a few commercial pen manufacturers who make roller ball pens in which the nib and ball are permanent parts of the pen body, and that employ a fountain pen as an ink supply. Here's a link to a web page that lists the various options: https://unsharpen.com/rollerball-pen-fountain-pen-ink/. Most of these use 'international standard' fountain pen cartridges, and some may be able to use 'international standard fountain pen converters' - whether this is possible comes down to whether the body is long enough to accommodate converters which are quite a bit longer than cartridges. I have a J Herbin rollerball pen that will only accept cartridges, so I have to refill the cartridge with a syringe. There are a few roller ball pens that employ other means of ink storage, for example the Noodler's Konrad Piston Filler Roller Ball.
I'm not aware of any roller-ball pen kits where the roller ball is a permanent part of the pen body rather than integrated into the replaceable ink supply cartridge, but I think that's really a matter of demand - if enough people want such a kit, it should be relatively easy for any of the kit manufacturers to supply - it would simply be a matter of replacing the fountain pen nib with a roller-ball nib.
That said, I suppose a creative kitless pen maker could come up with a design that uses the section/nib and cap portion of the J Herbin pen with a custom-made body.
