YEs you can do that, but you may not have a smooth VTEC transition at different RPM.

what do u mean with smooth? and i was thinking if the kick of the vtec will be any stronger with a setting like that?

A stronger kick is not a sign of good tuning. When properly tuned it should be very smooth transitioning form the low to the high cam. It will give the most power and best power delivery.
