If the plant is growing with good vitality, you can simply chop it back, keeping in mind that multiple stems will emerge from the cambium surrounding the wound. I do this very frequently with all kinds of plants. It works best if you use a very sharp tool to make the cut. About 15 minutes after chopping it back, wipe the wound dry with a paper towel & seal the wound outdoor/waterproof Elmer's glue. This helps the plant keep the tissues surrounding the cut hydrated & prevents the cambium from dying back and shrinking away from the pithy center (ugly scar).
Here is an Aeonium I chopped back. Note how the multiple stems emerged from the cambium around the cut, as I just described:
Wow! Tapla that is a beautiful plant! And one I'd never heard of before. I am always finding new things on the garden!
I myself have a very tall corn plant that used to be my mother's. I inherited it after she passed away. I accidentally broke a piece of it off one day while moving it. As Tapla said, new shoots came out the sides of where it broke off plus to my surprise a new one came up from the root. And I stuck the broken piece in water and it grew roots.
