I understand totally! The problem you've got is reducing friction. The
un-geared motors are worse, because your speed reduction train will inevitably
have much more friction than the reduction box Lego put in the geared motors. I
ended up also lubricating the reduction train (with margarine!). Connecting so
many together will also introduce a lot more friction, as you'll need a fairly
large number of gears to do it.
I found that 2 motors from 1 battery box did increase torque, though not by
heaps. But there's nothing stopping you connecting multiple battery boxes in
parallel too - just gotta be careful you always switch them on & off together!
Another idea may be to use a train (choo-choo, not gear) controller for power.
