You also need to establish the legal meaning of 'redundant'.
If you offered yourself up as redundant now would that mean that the company don't need you any more, you are superfluous? Would the new arrivals be better qualified than you and be able to slot into a vacancy that you are not currently qualified for?
This doesn't mean that the company can't choose to decide they are better off without you and then offer you an attractive severance package, note 'severance' and not 'redundancy'.
