I don't think anyone will risk putting you on their staff travel because:
1. Travel concessions are for friends and family
2. Staff can only change them 4 times per year
3. You should be paying the full pax fare as you are non easyJet staff. easyJet crew don't get travel concessions with other airlines.
As has been said to you in one of your other posts for trying to get easyJet travel concessions, you could always join easyJet then you will be entitled to travel concessions with easyJet.
