Can my boss fire me (as an apprentice) and re-hire me for the exact same position?

I have been wondering whether it would be possible to talk with my boss about this subject. As neither of us see the learning side as helpful to what I do, most of what I go into the academy for, to do lessons, I have done previously at work. And the in-work courses are asking me to divert time from work, to create something the company doesn't need.
So quite simply, I was thinking of seeing if it would be possible for him to fire me as an apprentice, and re-hire me but as an actual employee.

I don't see any use in my apprenticeship (social media & digital marketing, seriously, who needs that as a qualification?), I only took it so I could get a job easier with no experience.
My boss doesn't seem to care about the apprenticeship side of it, and said he didn't really want another apprentice. (So I can only assume that he wouldn't care either way)

If this is possible, how would I go about bringing this up as a topic?
Reason I ask, is because I basically see this as an "I want a raise" sort of question (which, yes, is one of my personal reasons for wanting to get out of the apprenticeship part). There's a few main reasons I don't want to continue as an apprentice; low pay, travelling to the academy once a month (it's just a hassle, which I have to pay for), in-work assignments don't actually correlate to the work I do, and the in-work meetings (with assessors) is just a hassle too, as we don't have meeting rooms, so if they come in on a date other meetings are going on, then there's issues.
