I think You can ask in
Scripting Help of AMX X forum how to write the plugin changing the mode of Your CS (normal, CSDM, another mod..). I think there might be the only way to change by plugin the files mapname.cfg according to the mapcycle (amx_nextmap) state.
I haven't had time to think more about this, but Your question is not related to CSDM2, but to the whole AMX X work, so You should ask there (link above).
