I don't know about you but I don't chill my wort while the pot is sitting on the turkey fryer. I bring it into the kitchen and then run my chiller in there. If he has cooking mits and has the ice bath ready to go then all he would have to do is take his pot from the fryer and put it directly in the ice bath.
Before I went to a 10 gallon pot I would ice bath 4.5 gallons of wort every weekend in my double sink with a 6 gallon pot. I got the temps down to 70-72 within 15 - 20 minutes consistently. I would go back and forth in each sink for the first 75 degrees and then it stayed in one sink until it was done. If you are gently stirring your wort and stirring the ice bath in opposite directions you dramatically increase your effeciency in temp drop.
With the use of salt it makes the ice last that much longer. If he had a tub and followed this method of active stirring and salt in the bath he is going to be able to do it. My own experience tells me that he can. Now if he is not capable of moving the pot then all bets are off.
What really stinks about all of this is that because I can't ice bath my pot in the sink anymore I have to use the chiller. Takes me about 10 or 15 minutes longer with the chiller.
EDIT: This was done with an aluminum pot. Better for conduction than SS
