[Chaos]

You're basically asking to create millions and millions of tiles of fleshed-out supermaps for the various continents, including various parts of the overworld adjusted to work on this new supermap-- such as caravans and the B.D.P. spawning-- alongside any game design elements that must be accounted for, and methods made towards ensuring that players can actually seek out one-another for roleplay without too much issue. Not to mention that 32x32 per overworld tile is not feasible if you want to integrate cities/villages/hot-spots, since each of them goes by their own sizes and will need to be worked around by the surrounding areas, not vice-versa.

I'm sorry, but this sounds like a pipe dream. The work required to see this through would take years to even decently realize, between mapping, programming, designing, etc. with the one programmer + few artist/mapping volunteers we currently have. Especially when a large portion of the 'advantages' can be replicated through other systems, which are much, MUCH quicker to implement.

Maybe with a constantly larger playerbase and a vastly-reworked 'world' on offer, we would be able to realize something like this and it would probably look good. But right now, assuming we can even put down behemoth maps like this and not ruin absolutely every advantage through monstrous lag, the best we could do without overworking ourselves is grass/path spam. It's just not something we have the capabilities to really focus on without major detriment to the game.
