Main Keyblade Run

Asking out ofcuriosity, is it possible to do a Kingdom Hearts Run or Challenge where you don't change your Keyblade/Keychain & use the OG Keyblade you have at the beginning of the game(s)

For example:

Kingdom Key Only Run Challenge in the following games: Kingdom Hearts, Kingdom Hearts 358/2 Days, Kingdom Hearts 2, Kingdom Hearts Re Coded, Kingdom Hearts 3?

I ask because I always thought it'd be cool to do like a "Canon" Playthrough & not have Sora using the Three Wishes Keyblade for example because canonically Sora uses the Kingdom Key.

I could see it being easy on the nunbered titles. The DS games are more so what I want to know.
