Yes, its not very difficult getting up to level 60, will have to do a bit of grinding or use trainers, but yea, that is more than doable.
Remember the more skills you use, the more levels you will be gaining, though grinding is sometimes inevitable, some skills are easier than others to grind, illusion is one of the easiest in my opinion, there is also the training exploit with followers and the companions which makes for some easy levels in skills you don't use. In the college quests there is the retuning the magicka wells, which can give you unlimited magicka for a few hours which makes grinding magic schools a good bit easier, though destruction and restoration is always a bit of a pain, being able to use unlimited runes and turn spells make it go as fast as any other school pretty much.
Just remember to try and train each level when you have the money, doesn't even matter what skill it is, though I would suggest a skill you don't use.
My current build i am using is about a level 64 planned build, level 48 if i went minimal, and uses 9 skills, probably my most ambitious build yet, excited to see how it will turn out.
Best of luck to you, and good luck!
