Upgrading Little Legends

I know Riot is mostly focused on creating more cash flow for TFT, but would you consider re-designing the little legend model? Perhaps you still pay to get little legends eggs, but instead of having to pay more for identical little legends, why not make their upgrades scale with experience points like in League? That creates more incentive to play more and attract a larger user base. Additionally, maybe you could also allow people to buy individual skins that they want? I know it's still in beta, but it seems like a fairly easy feature to implement.

Also I'm hoping we could eventually earn eggs just like we earn chests in League for leveling and getting S+ ratings on champions. I do really enjoy the amount of quests the developers have implemented along with the timeline of rewards. It would be nice to be able to earn a little legend skin to reward people for playing more. It also attracts more people to the game that might be dissuaded by the paywall.
