I concur with Mario and Etcjoe. And I’ve done this, making what was one measure across two. It often works but not always; depends on the style. The notation won’t be right, but the sound can be.

Nortonmusic.com has Expanded styles as mentioned that make it easier.

I can’t see any reason to have 3/4 enter into this. Maybe you could explain further.

Also, if you add MIDI chords by writing notes on the melody or soloist tracks, you can simulate what you want without doing anything with the time. Even if you don’t like the sound of MIDI as much as RealTracks, when mixed together, it could sound very effective.
