The answer to your question, as you worded it, is no.
This is a bit like asking can you put to 120vac light bulbs together so
that their total power would be more than 120vac? Of course the answer
is no, since you only have a single 120vac power source to start with!
(not to mention that voltage isn't a measure of power anyways, it more
closely resemblys an energy potential than anything else).
However, if you meant something like "Can you gang two lego motors
together so that their total power is greater?" the answer is most
definitely yes. When the motors are physically ganged together, and as
long as you spin the motors in the correct respective directions that
won't induce gear backlash, they will spin at the same speed, even if
the motors otherwise spin at different speeds. Of course, the resulting
mechanism won't actually spin any faster than one motor would (it may
spin slightly slower, in fact, as you've increased the friction
present), but any increase in friction should be more than compensated
for by the increased torque, with which you can drive a larger load than
you could using just one motor.
