Is a Fair # of Neighbors mod possible?

[K]

I rarely use mods, but there is one issue I'd love to get modded out.

-Some home provinces get three neighbors in random maps, and some get seven. Is there a way to correct this through a mod?

For a nation with resource heavy capital-only troops, having a large number of neighbors can mean the difference between having a lot of great troops for your empire, or just having a few.

I know I can just use established maps, with set home provinces, but this is less fun for me.
