Here's my suggestion:
instead of just one new continent, we have several around the central continent. The continents would range in size from Karamja to Kandarin. Each would be unique in race, culture, storyline, dangerousness, etc.
To solve the problem of future F2P crowding, F2P players could have limited access to some (but not all) of the surrounding continents in a similar way that the Kharadian desert and Karamja are set up.
Some of these new continents could have "extensions" of the current one. For example, a continent to the east of Meiyerditch could be very heavily influenced by the Vampires.
Some of these new continents could be entirely cut off from the main world until recently.
Concerning the scaling up of the world, I believe that this should be considered by Jagex as a possible RuneScape 4. A player vote on this issue would not be an entirely ludicrous idea. If the majority of players decide that the current scale of the world is fine, then so be it. We just move on. However, if the majority decide that a scaled up world is, indeed, the will of the players, then Jagex should implement such features.
