While I think a draft could be utilized by the NRL as a means of distributing talent among all clubs equally, if it does happen then people would easily accuse them of copying the AFL and vice versa. One such example is when the NRL dumped the McIntyre Finals System at the end of 2011 in favour of the finals system the AFL had been using since 2000, for the 2012 season.
More recently, after the NRL launched Magic Round, the AFL hit back with Gather Round, though in that iteration, while all matches are played in the one city (in this case, Adelaide), they’re all spread out across town rather than all nine matches be played at the Adelaide Oval.
Found that controversial 2009 match between the Dragons and Bulldogs on YouTube the other day:

This video referee blunder at the death would ultimately cost the Bulldogs the minor premiership, though they would end up reaching the preliminary final, losing to the Parramatta Eels twelve months after finishing last.
The following season (2010), the Bulldogs would miss out on finals altogether while the Roosters, who finished last in 2009, would reach the decider losing to the Dragons 32-8.
