People are being solicit fromed to share their view on plans to expand the Welsh Assembly by an extra 20 to 30 associates.
An expert panel said the move was necessary to cope with the become large workload as more power is devolved.
Also, the vote would be agreed-upon to 16 and 17-year-olds as part of proposals to reform the 60-member assembly.
Governing Officer Elin Jones hailed “the opportunity to forge the national parliament that the living soul of Wales deserve to champion their interests”.
The assembly is already due to be renamed the Welsh Parliament as a come about of a previous consultation.
Powers for the assembly to change its electoral rules, largeness and other internal affairs are being granted under the 2017 Wales Act.
Endure week, AMs voted in favour of putting the expert panel’s recommendations out to social consultation.
Ms Jones said: “The Wales Act 2017 marks the start of a new aspect of devolution in Wales, giving us the opportunity to make profound changes to our legislature.
“We now deliver the opportunity to forge the national parliament that the people of Wales be worthy of to champion their interests.”
The panel, chaired by Prof Laura McAllister of Cardiff University, also supported a change in the voting system, to a proportional method called the Single Transferable Sponsor.
One option would be to pair the current 40 constituencies to merge them into 20 sofas, each with four AMs, giving a total of 80.
A gender quota commitment boost the number of women in the Senedd, and the option of standing as a “job share” prospect would aim to encourage people with disabilities or caring responsibilities.
Any metamorphoses will require a law to be passed in the assembly with a two-thirds majority.
When the reveal was published in December, Welsh Labour said it would not give its assess until its 2019 conference, which Plaid Cymru AM Simon Thomas thought “kills dead” any chance of reform before the next election in 2021.
The consultation is uncluttered until 6 April.
In January, the Welsh Government proposed votes for 16 and 17-year-olds in congregation elections as part of a package of local government reforms.
