Caravan training with PPL+IR?

I’m 17 with PPL+IR and I’ll go back to school for CPL ME closer to my 18th birthday. My home country has 30+ caravans and a job is pretty much guaranteed once I have my CPL.

Until I go back to flight school is it sensible or even possible to do caravan type training with flight safety or one of the other providers?

Sorry if this is a stupid question.
