I'm sure there are several people out there already tinkering with altering the line of sight rules in 8th edition. The rulespack (and tickets) for this years Giant Fanatic tournament have now been released, and amongst them there is an attempt at a Systematic Line Of Sight (SLOS) system that I have copy pasted into this thread for your perusal.

We have been unsure on how exactly to tackle the new Line of Sight (LoS) rules at Giant Fanatic this year. The True Line of Sight rules (TLoS) as presented in the 8th edition rulebook gives us concern with regards to limiting peoples creativity when converting models for their army, or buying from alternative producers. These are elements of the hobby that we would hate to see diminished at Giant Fanatic.
A more practical problem is, that the new TLoS rules combined with the terrain, demand that we rethink how we use terrain now and in the future. Unfortunately it is not economically possible for us to update all the terrain we have already acquired which as above gives us some additional concerns using the TloS rules when we have the wrong tools for doing it.
We have decided that when two players meet at the table, then the starting point is that they should agree upon which LoS rules they want to use. They can either use the TLoS rules as presented in the 8th edition rulebook, or they can use the Systematic Line of Sight (SLoS) rules as presented below. If the players cannot reach an agreement, then the default will be the SLoS due to the reasons presented above.
Systematic Line of Sight
SLoS is an attempt to make a systematic system that as much as possible approximates the intention behind the 8th edition TLoS. It is obviously a simplification so the approximation isn't complete. All unit types and terrain are given a number representing their height which they can use to draw LoS from and other units can use to see them. A higher number can thus draw LoS over any intermediary units with a lower no. and can likewise be seen as well.
There are a few exceptions where a unit type is given two values, in these cases the values will be presented like this: x/y. The first value, the x, will represent how the unit draws its own LoS and the second value, the y, represents how other units can draw LoS to it and through it.
Skirmishers: All skirmishers have x/0. This means that they use their normal Troop Type for determining what they themselves can see or be seen by, but other units treat them as having a value of 0 when drawing line of sight through them. Infantry that skirmish would be 1/0 for example.
Large Targets: Other Troop Types that are also large targets (such as a Large Target Chariot) always count as being Large Targets for Line of Sight purposes.
1 War Beasts
2 Monstrous Cavalry
2 Monstrous Beasts
2 Monstrous Infantry
1/2 War Machines
3 Large Targets
2 Hills (per level)
2 Buildings (per level)
2 Impassable (in most cases)
? Arcane Architecture
(? will be specified where applicable)
Hills: Units standing on hills add the hill's value to their own. Cavalry on a one level hill have a value of 4 for example.
Obstacles: A unit in base-to-base contact with an Obstacle can see and shoot past it with no cover penalties.
Buildings: Units garrisoning buildings add the value of any upper levels to those drawing line of sight from the upper levels. 10 Infantry in a two level building would have a value of 1 for the five in the lower level and 3 for the five in the upper level for example.
Cover: If you shoot at a unit while there are intervening troops between the shooter and the target, then there is a hard cover modifier applied.
If the shooter is on a higher level hill, or on the second or above level of a building, then this hard cover modifier is ignored unless the intervening troops are also on the same level of hill or building.
Large targets can never claim cover from such intervening troops.
