We just have SEP class.
And you only need currency for carrying pax in the class students count as flight crew. Nothing stopping you not flying any thing in the class for 12 months then jumping in solo and flying off.
Done it myself in the C172 not flown one for 3 years and 9 months since I last flew a SEP. Day job is flying a twin TP. Then went flying with I might add full permission of the insurance company for a maint ferry.
