Byddai newidiadau hefyd yn cael eu gwneud i'r system bleidleisio ei hun, wrth i bob cyngor gael yr opsiwn o ddefnyddio system y Cyntaf i'r Felin neu system pleidlais sengl drosglwyddadwy. Byddai angen i gynghorau ymgynghori â thrigolion lleol cyn penderfynu pa system i'w defnyddio.
Changes would also be made to the voting system itself, with each council being given the option of using a First-Past-the-Post or Single Transferable Vote system. Councils would have to consult with local residents before deciding which system to use.
