It wouldn't take forever to be honest. Fuinjitsu is amazing. The Amplification Summoning Technique copied the entirety of the dog is was imbued into with no problems. If you possess the know how, you can make anything happen. Look at the Fury Technique. It uses Natural Energy, yet none of the members of the clan it originated from were sages or could sense Natural Energy. Anything is possible with the know how or with enough trial and error with a pinch of innovation.
