I´m not trying to stop you, but aren´t actually looking for trouble here?
Before you start all this mess, please ask yourself whether the modifications on your scratch build will be visible withe the sole eye of a human. I mean we´re talking 1/24 here and youare not about to change a wrong or misplaced decal...
When you answer this question with a sincerely "Yes!", I´m more than eager to see more of this scratchbuild-fest it will be.
Regards and good luck
Robert
