An $n$-level quantum system is an $n$-level quantum system, no matter if it's stored on $\lceil \log_2 n \rceil$ qubits or on $\lceil \log_3 n \rceil$ qutrits or other combinations of qudits. There would be costs to interoperating computers that use qudits with different numbers of levels, because you have to do work to convert between them (e.g. having to ...
