Details such as salary and job profile are still being cleared by a steering committee of Welsh councillors, advised by the Association of County Councils.
The new secretary is expected to command a budget of £870,000 and will report to the £95,000-a-year secretary of the new Local Government Association for England and Wales, of which the Welsh body will form a part.
The first meeting of the Welsh association is scheduled for the end of February. This is expected to decide on the association's aims, structure and constitution, just weeks before its start date on 1 April.
Instead a network of both permanent and ad hoc member panels could formulate policy proposals, meeting at their discretion in public or private.
A special committee - perhaps with one member from each council - could provide political co-ordination.
The paper also suggests that the full council should meet twice a year, consisting of the members of Welsh councils nominated to the general assembly of the LGA for England and Wales. This would give Cardiff, for example, four delegates and seven votes.
The association 'will aim to be proactive, to set the political agenda and initiate its own proposals', says the paper.
