Replacing steering wheel of Citroen C5

[Kenan]

Is it possible to change steering wheel of C5 and put some other model, maybe of P508 or maybe of some DS model

Not really, the steering wheels are specifically designed for each vehicle and its equipment and electrical system. Plus they contain specific airbag modules that are designed for each type fitted into the unit, ESP angle sensor and then the steering wheel controls that probably won't be compatible.
