No. Diode or Boolean ORs are actually rather different from a basic mixer. With an OR gate (of either type) the module reads the incoming gate signals and combines AND regenerates a resulting +5V gate. In a diode OR, this regeneration doesn't happen, but the functionality is still the same: combine gates to get a "composite" gate. This is different from a unity-gain mixer, where incoming signals are simply mixed together...this won't arrive at that "composite" gate result.
Another module this all gets confused with would be adders. In their case, you input various CVs, and the output is the arithmetical sum of the incoming voltages. These won't work to combine gates AT ALL...what you'll actually get when two gates coincide are the +5V amounts when the gates aren't coincidental, and +10V when they are. However, you CAN still arrive at a single gate by feeding the adder to a comparator and setting its threshold to, say, +6V so that whenever that level is exceeded, the comparator will fire off a gate. But it won't be a true "composite" gate; rather, this patch would only fire a gate off during those coincidental points...which can ALSO be useful, but it's not what an OR does.
