Hi folks,
Cuis is a Smalltalk-80 system. My suggestion is to go the Smalltalk way.
(There are tons on books and references on OOD with Smalltalk).
So far I haven't seen a problem where Traits offered a clear advantage
over Composition / Inheritance. Traits implementations for Smalltalk are
poorly integrated into the system, and the few people who try to use
them keep reporting problems with the tools and the environments, for
example, in Pharo, after many years. If people really want Traits,
please commit seriously to supporting them, adapting the system as
needed, to keep the current level of quality of the programmer's
experience with the system.
If a person or group does this, then Traits could be a useful optional
package for Cuis.
Cheers,
Juan Vuletich

That would be the one I'd port, if I was going to the trouble of porting; the version in Pharo will be a lot harder to disentangle from Pharo.
