I'm not familiar with cnpc data handling, however capabilities are just NBT data, for example you can get your own doriki using the following command /data get entity @p ForgeCaps.mineminenomi:entity_stats.doriki
with ForgeCaps.mineminenomi:entity_stats.doriki
being the path for it, assuming cnpc allows you to change an entity's NBT data (or spawn them with that to begin with) then yes it would be possible, however they still wouldn't be able to use fruit abilities, this is limited to factions checks, doriki and haki powerscaling.
