I agree that he needs to count on spells, but also...
Invisibility creates the possibility to Hide, but is not Stealth.
Enhance Ability needs a reasonable Persuasion to work with, since it gives advantage.
Knock is really loud!
At 4th level, you can Levitate twice, and can't Fly.
I mention this to say that I think for his character concept to work, he needs to think about which skills will be rolled for all the time (we see a lot of Stealth and Persuasion checks) and which are rare enough to rely on spells. Also, which spells can replace or buff hugely, like all the various Charms.
Yes, but this is why I followed up with offering the Half-Elf, Prodigy route. Between spells and the extra skills from race and feats, the wizard will have more than enough skills and tools to do what he needs. Layered with all those spells, it's a pretty good mix.
