Can I use a larger compressor?

Think of the compressor as a glorified suction pump, the bigger the pump the bigger the suction it will deliver. Lower the suction pressure and that lowers the evaporator pressure and temperature.
If you lower the pressure too much and if you lower the evaporator temperature too much complications such as evaporator freezing up may occur.

Depends on just how much a difference the temperature difference is.
In principle it should not make a high difference but it must be allowed for.

Thanks. I guess I'll give it a try then.
