A tank of liquid nitrogen is not just an alternative, but a much better substitute, IMHO. The problem of gradually cooling inside a isopropanol container can be overcome by using a box full of dry ice (-79°C as I recall).
So, for every row on the dish protocol, the entire process is scaled up a discrete value. In the case of 100mm to 150mm, the values are scaled up by about 2.76 across all values: (a) 152/55 = 2.76, (b) 1.52e7/5.5e6 = 2.76, (c) |avg(30.4-45.6)/avg(11-16.5)| = 2.76 (as answered in comments)
