To rephrase, when I'm saying "using a greatsword", I mean having a damage die expression of 2d6, with the related heavy and two-handed keywords. I don't care if narratively it's a dagger, as long as you can't transfer that mechanical expression to another character. That's what I mean by saying it's better to make the reskin a function of the character, not the equipment.
I understood you. My point is that if the character narratively is holding a dagger and gets the heavy and two-handed keywords his character, where do those properties come from? Abilities come from feats, class, race, etc. Are you granting that PC the ability to hold every dagger in a two-handed manner and somehow gain the heavy property? Is it only that dagger?
Granting it to the PC. I grant special exceptions to my PCs all the time. They'd be roughly equivalent to boons, I guess.
Plus, no matter what size and how strong you are, a greatsword is not meant to be used with one handed anyways. A dagger is good for slicing and stabbing based on how sharp it is but a greatsword is meant to chop. You want a dagger to have a more even weight distribution. You want a greatsword to be top-heavy, to an extent. Try holding a broom one-handed by the handle and swing it like a weapon. You can obviously pick up the weight of the broom but you're either creating a moment by being offset to the center of mass and need to re-adjust or you have a hard time resisting the moment of inertia because your hand is on the center of mass.
Then for me it would really depend on what the ability was and how it worked. It would have to be magical to add that much weight to the dagger, and I'm not sure how you would even hold a dagger hilt two handed.
