This topic was discussed during WPC 2015 for starting daily Sudoku/Puzzle. We can start it will daily Sudoku. It will make regular visitors to LMI website.
Few suggestion below
It will be at the same lines as Guest League works on the SudokuCup.com website.
Some puzzle authors (preferably all Indian authors) will post there Sudoku on there respective blogs and then post link to LMI facebook page. It will also help LMI facebook page being active.
After delay of 24Hr. the Sudoku can be played online on LMI website. In face online interface is not possible for any Sudoku type then link to the Sudoku page will be post.
Here responsibility of posting correct Sudoku is with the Sudoku author.

Should this thread be here, under WPSC2017?

No.

I don't want to put this thread in public forum. It is only for internal LMI discussion. Admin can move this thread where all of us can discuss this.
