If there is a limitation, I would create a weapon, similar towards the Omnitrix but more so gauntlet like so it still fits the Weaponary agenda but with it I can scan any sort of Skills, Knowledge & Memories. As the weapon is entangled with my DNA thus making it hard to remove, I could use it subconsciously in order to mimic any sort of Skill I so desire. With enough unlocks of Skill replication, I can choose to upgrade them further if I so desire.
