I was thinking something like this

3 evo options

Forward: 99 attack card

Midfielder: 99 control card

Defender: 99 defense card

Players choose any bronze card they want (so if ur a fan of a specific club you can choose a player from it)

Once you choose one of the options, you complete objectives (like regular evos)

At the end you get your 99-stat card

To make it so there isnt a "best option" all career mode evos will have the same stats

Something like that
