need help juggling voices

I have a lot of measure in this score like this one.

I want to take the 16th notes in the bass clef and move them to the treble so they
can be imploded with the 16th notes already there.

Here is how I know how to do it, but it's pretty tedious.

1) select the notes in the bass and exchange voice 1 and 3
2) then change selection filter to only select voice 3
3) then select the notes in the bass voice 3
4) copy them to the treble clef
5) select the treble clef measure
6) implode

Is there an easier way?
