Remove the beard and make him/her wear lipstick so he/she has no discernable gender. If his/her face was not quite dark enough to be black and not quite light enough to be white I am sure he/she, could, with just a little imagination pass as just about anyone. Since he/she is the "Winter Holiday Person" he/she would show no favouritism or bias toward any particular race, creed, religion or sex(ual orientation). He could hand out toys; but not war toys, candy, but nothing containing chocolate that might offend Moslems during Ramadan.
He could have elves, but they would have to be of average height so as not to be seen as exploiting or making light of the vertically challenged. Replace the reindeer with an environmentally friendly electric/ natural gas hybrid engine and even the greens could feel welcome to celebrate whatever holiday it is they celebrate at this time of year. There it is a Santa/Sandy we can all call our own.
