While plurallet may describe someone's experience of being both plural and singlet, fluctuating between the two, or being inbetween them, plural non-system may fit more to describe a collective of individuals sharing a body who, for some reason, do not identify as a system. As such, the terms may be synonymous or overlap, but may also be distinct.
