Perhaps an NPC that would exchange upgrading stones to advanced ones.
i.e:
25 x Armor Upgrade Stone U60 (Blue) =/for 1 x Advanced Armor Upgrade Stone U60 (Green)
25 x Weapon Upgrade Stone U60 (Red) =/for 1 x Advanced Weapon Upgrade Stone U60 (Purple)
Same system would apply for U65, and U70 when the cap arrives. (amount of stones required to exchange can be discussed)
Haven't thought about any negative consequences other than the sudden boost to those with incredibly large stacks of blues and reds. This isn't necessarily making things easier, rather making things fairer for those spending large amounts of time farming.
