The problem is unless it's less than a couple of amps it's hard to regulate the voltage, since linear regulators are extremely inefficient so you can only use them for quite small currents, SMPS's are quite difficult to design and adding more transformers is rather illogical, so I'll be interested to see how you plan to change the voltage. Also if the other appliances only use a small amount of current (making it reasonable to use linear regulators), then the transformers are probably several times bigger than they need to be.
