What about Urahara Kisuke? or Shinji? Both of them have more reasons to hate Aizen...
And last I recalled, Ichigo got his ass kicked by the 4th Espada. So taking on Aizen is just suicide.
Well, Urahara has been proven that his Zanpaktou specializes in making barriers and he couldn't help train Chad and had Rengi do so instead. He only helped Ichigo along time ago by mental/physically strengthen him and tought him only a simple Spiritual release blast attack that all soul Reapers can use, so that really didn't count.
For Shenji, getting cut by Touzen (sorry forgot his name) was a sign of him not being Mr. Bad arse every one thought he was, Aizen didn't even flinch a muscle when Shenji tried to attack him and i really hated how unprofessional he was by doing a rush charge attack on Aizen like that.
About Ichigo losing to the 4th Espada, well come on Ichigo has only been a soul reaper for about a year or 2 versus other who have been for hundred's of years and i don't see/hear them defeating 2 liutenants, 2 squad captains (Byakuya being one of the top 5 strongest/experienced captains in soul society), leader of the Bounts (Kuiya), Grimmjaw (5th Espada)/some other Espada, and saving head captain Yamamoto from Amougai's deadly shield trap.
I believe Ichigo will learn to control his new hollowed form and his inner hollow said they would meet again in the future. I just have a feeling Ichigo will be like the strongest Vizard achieving and master that form he had during his fight with Ulquirra and making him like a Vasto Lorde of Vizards. (Vizards gain more power by having more hollow and i believe hollow like state as well but the Arrancars have been proven that the one's who have the most human like appearance "Espada" are the strongest, see the parallels Cloud.)
