Is it possible - of course it is - for about 2 hours lol!!
You would only do 1 man a good day at 35o litre - some probably would run out even then, but if you halved your cleaning time by having 2 of you, maybe you could do same amount and go home at dinner

But you would be paying a wage, maybe get some barrells to fill another 150 litres or so at dinner and do a bit more, or stick another 150 litre tank in or get a 500 litre or bigger...
