umm there is a few errors
Design, materials, construction process, etc. When shiro makes a projection he has to perform all those acts to make sure the weapon that comes out as a product is correct. Since its a giant version, the structure would have to be remade to prevent bending/etc from its own weight, It would have no history as a weapon in time, nor the smithing method never existed in history, so he wouldn't even be able to accurately reproduce the traits of it
He also probably can make his own sword, but tracing it would make its quality extremely low since its not a NP. If he traces a long sword, it will be completely weaker compared to tracing Excalibur
Archer modifying caladbolg is possible however. Shiro can make alterations to his weapons slightly without much quality loss. At the expense of making caladbolg an aerial affiliated weapon, it lost most of its melee abilities. With kansho and byakua, shiro could make them a bit longer/lighter/sturdier, but the changes would have to be somewhat small so the product is still similar to the original
here's why he cannot do that projection
* It costs too much mana to make a giant weapon that can crush people
* He would not have the strength to even pick it up. In the nine lives case, he was able to also amplify his body by copying hercules's NP
* The image would be incorrect and be very breakable*
* It would not be too powerful since it stems way too far from the original
* Would take too long to project if possible
* Shiros mind would probably overload his magic circuit in the construction...
Although it would be awesome to do, he simply cannot project a giant weapon freely... at least without seeing one in the first place
this is considering his magic circuit, and mana supply could even handle doing that
