Parallel bars as High Bar substitute?

Would it be acceptable/ too dangerous to remove one of the bars on a parallel bars set and use the other as a high bar?

 

This is for the Rope Climb elements PE16 and PE17.

 

Any alternative suggestions welcome too, thank you.

Should be no problem here. I swing on and around a single pbar comfortably, and I am certain I outweigh you

:-) I'll have to change that ;-) Thank you for the confirmation.
