Practically speaking, Most likely not possible. Hypothetically speaking, It's possible, but we won't know without being able to try (eg, A21 being publicly released)

Based on what I know from observing the dev logs and reveals and all that, I'd say it's about 99.99% chance that it won't be possible to directly import your character forward; The structure of the save file is definitely changing in some major ways with the changes to the skill tree to accomodate the crafting book system and all that stuff.

That said, There's nothing stopping you from just writing down your character level and all that and then 'cheating' in all the stuff from your current character onto a new one and saying it's the same.
