But I guess your suggestion of internally mapping one of the two versions (2000 or 2005) to "GB13080", based on the value of a new System property,  version 2000 being the default, could be a better approach.
We could start out by adding GB18030-2005, as you suggest.

A potential next step would be to rename GB13080 to GB13080-2000, with 
"GB13080" as an alias. As it stands, the charset name is "GB13080" with 
"GB13080-2000" as an alias so it should be compatible with code that use 
Charset.forName. It's possible this change may be noticed by code that 
does lookups in other ways or expects getName to be match the name 
specified to forName so that would be a feature release only change.

If there is a strong need then it should be feasible to have a system 
property to change GB13080 but maybe it's not needed in the short/medium 
term when some operating systems are still using -2000.
