I think the problem with that idea is that it is hard to schedule too many games between smaller nations and larger nations because the rugby calendar is pretty packed and the professional leagues and international tournaments such as The Rugby Championship, Six Nations and the various Spring Tours are what drives revenue for the big rugby nations.
Whilst it might be good experience for the smaller nations to get to play the larger nations more often, it would decrease revenue from the sport which would affect every nation.
Due to the physical nature of the sport and matches needing to be scheduled about one week apart, it is hard to hold any sort of tournament in a short period of time.
