yes it'll hurt to have the bearings touching!
that cutting was a bit ambitious and is in fact a terrible idea.
Ah well, now you need a new hub in just a few days of driving.
the bearings want to be apart by at least one race width in order to properly spread the load.
otherwise chances are the attached rim (especially if it's an offset rim)
the lever will wallow out the hub and the bearing will drop out..
being left with just one supporting bearing and the next curb will break it completely.
BUT you could have (and in fact should have) use a hub for a stepped axle instead.
(if that's the correct size, you can just fit one 1" bearing on one end to achieve the same;
also remember to put a bearing spacer between the two
that way the inner bearing can gently embrace the 1" part while the outer one snuggly wraps around the 3/4" threaded part and also prevents the hub from moving inwards.
