Global vision setting

[Imp]

Guessing this is not possible but thought I would ask
Would it be possible to code a random factor into vision range.
Not realy for high vis games but low vision so night rainstorm etc.
Rain lets up for a bit moon comes out from behind cloud vision increases slightly.
Oh heck he can see me now
If possible say a small chance to change with a bigger chance then to shift back so global setting would be the average.

If pos could also have a setting so slowly increases or decreases, dusk dawn morning mist burning off etc

I play another game that has this and I don't like it. It is optional for that game.

If vis is 3 and your scouts spot a threat. You move a unit 4 hexes from that. End your turn and vis chnages to 4. Bam your unit is destroyed.

Well, would be realistic thoug How many night attacks went wrong because fog fell? How many went wrong because moon shined unexpectedly? etc.
