Oh, that part I understood!

When I said "all-emcompassing representative of the Card system", I was refering to her ability to equip other Heroic Spirits, not just Cu Chulainn. Unlike Kuro who is indeed stuck with Emiya, she could have been more than female Lancer, something akin to a Super Cosplay War Ultra character (check this game, it's free and it's pretty whacky and awesome for a fangame): installing Assassin and Rider for Quick Attacks, Caster and Saber for Arts, Archer (Gilgamesh) for Buster, and Cu Chulainn for EX because it's her main class just some examples^^

But it would probably be a massive budget dump on one character. Your idea is probably cheaper while being functional!
