I’ve only ever come across Albizia as a wood for turning, the problems I encountered with it was that it splits a lot on the end grain and had lots of checks in it also it was quite difficult to machine as the grain is very tightly interlocked but I could have just had a not very good piece??
As you’ve said that if it doesn’t work then it’s not the end of the world so just go for it and see how it goes I’ll be interested in seeing how it turns out......
Also love the shape, but @Jabba_the_gut has a really good point
