Yes its ok.
Be careful so you dont break a branch = have tape at the ready.
Whats happening is your changing the apical dominance. But I have done this in the past and what I noticed is that, lets say you have two equal branches and you bend them straight horizontal and lets say ones at 9 and ones at 3 but the one that is at 3 falls down to the 4 o'clock position. That 4o'clock branch tends to get left behind and doesn't develop as much as the equal branch on the other side. So keep them all level (support them) if you do this, until they heal and they re-establish equal dominance around the plant.
Or if you dont go to that extreme its ok to bend a few here and there. In a couple of weeks ill post a couple of pics of my supercrop job i'm about to do. They were ready to go into flower last week.
