Growing/making new plant from leaf

Y-Shaped Senecio

Hi, I have finally been able to buy a couple of Senecio radicans glauca - fish hooks. I noticed that one of the leaves rather than be the classic fish hook shape is shaped like the letter Y.

I got excited when I saw it as I would like to try to propagate this to make a new variety of plant with Y's instead of hooks.

Is this any other way rather than tissue culture as i don't have access to that. Would love to hear any ideas you may have. I live in Tasmania, Australia.
Looking forward to hearing from you,
