If the Beta setup is the same as ours, there is no need to and in fact it would be a bad idea. The alternator can already produce about 135A at idle and this is a big load on the crankshaft bearings/pulleys/belt etc. The engine, belt etc struggles a bit with this due to the high torque load. By about 1000 engine rpm the alternator can make nearly full output. If the engine pulley was made smaller, all of this would get worse and the engine would struggle more, the belt more prone to slippage and all for naught. If the system is working properly, it is excellent and no need to tinker. If it is not working properly the correct course of action is to fix the fault rather than do stuff to disguise the fault.
