FOTS Naval overhaul proposal (need advice on feasibility)

I'd like to make the naval battles more realistic, at least strategically.

How feasible would it be to redo the strategic naval portion of the game to do the following?

Unless a naval force is blockading a port naval battles do not occur automatically. (They no longer occur by moving your fleet to another fleet.)

Instead, when a turn ends, any of the active player fleets that are within a certain distance of an enemy fleet have a percentage chance of a fight occurring.

Realistically, naval battles didn't always occur when a commander decided they should. Bad weather, bad luck, and bad timing made it very difficult to actually engage a force, instead of the laser GPS guidance that the game now portrays.

If that's possible (and I doubt it, without some core changes), then I'd want to look at changing the percentages of a fight occurring according generals stats, the ability to set fleets to "pursue" or "avoid" fights to change the chances of a fight even more, and finally modifying the A.I. to take into account the changes.


Advice, thoughts, and input are appreciated.
