Is there any approach that forces Cplex to output original maximization probem in mps format (we only want mps format) ?

The MPS file format does not define a way to specify direction of the objective. That is why CPLEX always writes the model as minimization problem. There is no way to change that.

On input CPLEX accepts additional tokens to specify the objective sense, see here.
