I like the idea of changing the contract structure to make it more incentive based, potentially across all the organisations involved with SRP (Super Rugby Pacific) and opening the door for cross-country player movement.
Have three mandatory base tiers of contract - development squad, main squad and marquee players. Only allow up to five marquee player contracts per squad. Maximum 2 years deals except marquee players who are 2 years plus a 1 year team option.
From there the incentives are baked in on number of games played, number of games won, team making the finals, selection in a national squad and the biggest being national team match payments.
The main problem I envision is that France and Japan would just come knocking with their big fat non-incentive based contracts which are more appealing.
