How about this (baby steps)
Step 1, find a Salak that will reliably produce plenty of fruit in sub-tropical South Florida, USA; it would be great if a local nursery, such as Excalibur, were to sell it. Something tells me that finding a tree like this may not be an easy feat.
Step 2, once such a Salak tree is finally found, have the University of Florida genetically modify it, to produce a Salak palm tree that has none of those "vicious thorns."
In my yard I have a few, beautiful palm trees with extremely dangerous thorns that once sent someone to the hospital, after a severe puncture. So, if I were to find a productive, quality fruit, Salak Palm for my area, I would probably be getting it in a jippy.
I eat Palm thorns for breakfast, lunch and dinner baby.
