No, a larger bowl would not fit into the machine. One can purchase extra bowls (which I have done) from Chocovision, but they are just for convenience, not for quantity. The "holey" baffle gives the larger machine more effective capacity, but although I read that Chocovision was developing such a baffle for the Rev 2, that never came to be. So to get more capacity, the user can either (1) heat more chocolate separately and pour a little of it into the tempered batch--but I found it a nuisance to try to estimate how much was not too much to add or (2) heat more chocolate separately to the start point for tempering (113 F. for the dark I use), use what is tempered in the machine until the level is low, then turn the machine off and back on to start the melt cycle again, and add the extra melted chocolate to fill the bowl-it sounds ridiculous, but since the extra chocolate is quite warm, the Chocovision goes into the temper cycle right away. Obviously a larger machine would be great, but I just don't do batches large enough to make good use of it.
