Dual classing enhancement - not a request

Seeing a few threads recently on dual classing, I thought I would spin up my feature requests that I don't think can be implemented within the current game engine, unless paying down the technical debt that Trent said has been occupying the team of late has had a signifiant refactoring of the engine. Still, in the idea world, I would like...

1) Per PnP, there were very few restrictions on dual-classing. I want to dual-class any primary class into any other - although would be happy to accept no dualing from a fighter into another clear warrior class, such as Paladin to Ranger. Monk to Sorcerer should be well within scope though ;~)

2) Given the limitation that we can only dual along the lines of a valid multi-class, I want to dual-again! There should be twelve valid routes to triple-classing (if you happen to have the magic stats):

fighter -> cleric -> mage
fighter -> mage -> cleric
fighter -> mage -> thief
fighter -> thief -> mage
cleric -> fighter -> mage
cleric -> mage -> fighter
mage -> fighter -> thief
mage -> fighter -> cleric
mage -> cleric -> fighter
mage -> thief -> fighter
thief -> fighter -> mage
thief -> mage -> fighter

The PnP rules said you could "dual-class" as many times as you liked, as long as you satisfied the 17-stats requirements for additional classes. Indeed, in classic 1st Edition AD&D, the Bard was a (very different) class that was available /only/ as a third class - the original prestige class!

I am probably more interested in (2) than (1), but suspect the file format of the game engine means that neither would be possible without totally rewriting the character code and data structures.

(I do remember using paladin->ranger silliness in the classic Gold Box games)
