King Upgrade Paths

Hi all,
I recently came up with an idea for KnC, though I will confess that it is complicated and probably not viable as it would require a massive time investment (I'm talking huge). Beware a flowchart follows, but I'll ease you in with a pretty picture:

Now I should begin explaining; this is an offshoot from the "a mighty hero" thread and it concerns the king unit and veterancy. It also assumes that the king works like a demigod in terms of leveling (or if you haven't played demigod, try DotA). Essentially my idea is that for each faction a king is chosen from one of three techniques before the game, then ingame, when they reach a certain level (Im saying 7 on an arbitrary basis), they can choose to select a style specialisation, and will change class on the basis of that.
The following example, using the afore-warned flowchart demostrates all possible upgrade paths for an Empire King with the Ranged technique. Each time the King reaches a level thats an interger mulitple of 7, he may pick a style specialistion: Either Traditional, Tactical or Technological.
The flowchart;

Hero types:
Level 7:
Farshot [Trad] : Basic Archer
Rifleman [Tech] : Basic Rifleman
Commander [Tact] : Archer Commander (Buffs nearby archers etc.)
Level 14:
Mastershot [Trad/Trad] : Advanced Archer
Crossbowman [Trad/Tech] : Basic Crossbowman
Ranger [Trad/Tact] : Stealth Archer
Sniper [Tech/Tech] : Advanced Rifleman
Tactician [Tact/Tact] : Advanced Archer Commander (Better Buffs ie, groundspike deployment etc)
Engineer [Tech/Tact] : Anti-Mech/Structure
Level 21:
Deadeye [Tech/Tech/Tech] : Ultra Rifleman
Keeneye [Trad/Trad/Trad] : Ultra Archer
Strategist [Tact/Tact/Tact] : Ultra Archer Commander (Serious Buffs)
Recurve [Tech/Trad/Trad] : Multi Shot Advanced Archer (+ special shots ie, flaming/explosive arrows)
Repeater Crossbow [Tech/Tech/Trad] : Rapid-fire Crossbowman
Shadow [Trad/Tact/Tact] : Advanced Stealth Archer/Assassin
Sieger [Tech/Tact/Tact] : Fortifications Buffs/Debuffs
Rocketeer [Tech/Tech/Tact] : Long Range Anti-Structure/Monster
Master Ranger [Trad/Trad/Tact] : Stealth Archer/ Scout
Pros + Cons
(As I see them)
Pros
-Customisation brings personalised tactics and strategies.
-Depth and replayablity due to number of possibilities.
-Its cool.
-Matches are unlikely to be the same.
-Brings sense of progression thoughout games.
Cons
-3 styles gives 18 classes per technique (19 if you count the base hero), this gives 54 (57) classes per faction, 162 (171) in total. This is a huge number.
-Balance nightmares with overlapping roles and some heroes compleelty hard-countering others or tag-teams of perfectly synergetic heroes.
So what are people's thoughts? In its current state this is pretty much unworkable due to large numbers of classes. Is this idea worth pursuing? Would you like it ingame?
Sidenote, I also planned out trees for the combat and magic techniques for empire, would people like me to upload flowcharts for them as well? It wouldn't take as long to make now that I have the template. Name suggestions or alternate classes are welcome, I'm not happy with some of the advancement paths.
tl;dr
Why? I even gave you a pretty picture to ease you into it......|||it looks a bit complex just by skimming over this, having a dozen upgrades with multiple requirements and pathways from one to another, it almost seems like an RPG character.
don't have enough time to read through it properly, but will do later and give more concise criticism. :)|||You are probably right that its a bit complicated, it certainly looks like it when laid out like this .
In a game the player would be given three choices at differnet times, each choice would have three options, so from the players point of view its fairly simple, just pick the upgrade path you want each time.
I finished up the Magic and Combat trees and made a template if people want to have a go themselves....

Oh, and the template:

As the Ancients seem to be magic based, perhaps taking the techniques as Dark, Light and Twilight and the styles as Summoning, Destruction and Alteration might work.
