If you were keeping it for yourself, do whatever the heck you want. Since your intent is to pass it on, however, don't try and pass it off as something it isn't. If you have two identical bikes in exact same condition but one is a clone, the clone is worth less. You may be honest and tell potential buyers the backstory and they would expect a certain price break for a "clone" over an original but what about the next time the bike changes hands? At some point the clone gets sold as an original and some buyer pays more than they should have. This has been a problem in car world for decades. Its also been an issue with bikes, and bikes are more easily cloned and that's one reason original paint and decals are so valued.
