24 volts for heated bed and 12 volts for everything else?

Having switched to a smoothieboard after melting the power inputs to my RAMPS, I am interested in running my heated bed at 24V to reduce the current load. However, I’d like to not have to replace the 12V fans etc. As the big mosfets have their own (seemingly) power input, it seems possible that I can have 24V and 12 at the same time. Am I dreaming?

Yes just provide 24v to the big mosfets power input, and 12v to the small mosfets power inputs, for example.
