My ideas:
1) Elf, rogue-adventurer, knife thrower, agile character. - No, because there is no proper knife-throwing mechanic, and there are not enough interesting skills for agile characters in general.
2) Archer, partially a nature mage, hunter. - No, because there are no suitable skills, and making just an archer would be boring and uninspired.
3) "Ascetic knight," one-handed sword, armor, musician, wanderer. - Most likely no, because the goals don't align.
4) Elf-knight, two-handed sword, leader. - Possible.
5) Knight, sword and shield, local hero, ideological heir of Larte. - Possible.
6) Knight, spear and shield, horse, wealthy. - No, because it would require traveling with a scoundrel, and there are no horses.
7) Elf, forest knight, nature magic, mace and shield. - No, due to the lack of necessary skills.
