Maybe you could iteratively set the MIP gap and then call postProcess and solve, like

//preparation

cplex.epgap = 0.9

cplex.solve()

cplex.postProcess() // with the execute block after main the writing should be triggered

cplex.epgap = 0.8

cplex.solve() // it starts from the previously optained solution, since nothing has been ended

...

and so on. Maybe you could also decrease the epgap-parameter in a loop.
