It is certainly doable and your skills may be directly applicable to piston aeroplanes - that is, there is no formal obstacle to being hired right away. At first, you will be working as an unlicensed mechanic, which means you can't sign off your own work - a licensed technician has to check what you've done and sign it off for you. To get an aircraft maintenance license, you need 2-3 years on the job (depending on the license category you apply for and on whether your prior formal training is recognised as relevant) and about a dozen theory exams (exact number depends on the license category, too). For the exams, you may study on your own or go to school.
