@King Rio:
You would have to read in the map from either a wbs file or another kind of storage, and then loop through it and explicitly set every tile to the value in the data. Not that difficult to do, I'm sure many people here could do it. Unfortunately I'm too busy, but I might give it a try next week.
@Angus Khan:
Yep, that wouldn't be a problem. However, you could also consider using the default console command to regenerate resources.
