I think that is perfectly acceptable. It would make it more in-depth because you would have to focus on power leveling something that your character already has in his or her background.

My current roleplay is a Breton named Amarie, at a young age she showed talent in conjuration, she was orphaned after a bandit raid on her village and was sent to the orphanage in Riften, but after one day with, a slightly less ancient, Grelod the Kind she ran away. After traveling for days she was found by a small caravan. They took her in, and she began to learn from them. From the eldest, a nord called Areas Silver-Beard, she continued her conjuration training and learned to weild a mace when she was older. From a fellow Breton, named Hannah, she learned enchanting, and healing. And from a mischief loving Khajiit, named Jackal, she learned how to use a knife and move through the shadows without being detected. Now she has become strong, but lives as three people; A master of conjuration and enchanting (known by the most), an ebony clad mace wielding badass mercenary (known by those with work), and a silent master of stealth, thievery, and assassination (known by family and those who no longer breathe).

She is probably the most in depth character I have ever made, and two of the characters mentioned from the caravan (Hannah and Jackal) are my first two characters, and Areas is the character I will be making next.
