Changing the spoke tension shouldn't affect the way the bike rides unless it's so low that they're actually going slack (which would be considered a failure). The stiffness of a spoke is the same whatever tension it's already at.
Tyre pressures of course will make a big difference. I agree with you that it's unlikely that the small amount more flex from a lower BB drop would be noticeable.
