Yes, but this can be accomodated in the urrent TCS as two concept instances
(one for each Code-name), each having "is congruent to" definitive
relationship to each other.  The alternative is to break the 1:1
Concept:Name design limitation of TCS -- which may be worth considering for
other reasons as well.

Agreed, but without breaking the 1:1 Concept:Name design of TCS, they can be
accomodated in the schema as one name literal, two concepts, two name
objects.
