Interesting.
I had an idea for a "new" lightsaber style, sort of how Vapaad is an offshoot of Juyo, this would be similar.
I was going to call it "Jun-Sai."
https://swfanon.fandom.com/wiki/Form_VIII:_Jun-SaiIt was to be, basically, a Lightsaber version of Gunkata -
https://www.youtube.com/watch?v=bcs2En6tGRwI don't remember how i came up with that name, but it may have been a combination of the two terms:
Jung-
https://starwars.fandom.com/wiki/Jung_maand Sai -
https://starwars.fandom.com/wiki/SaiA quick google also tells me "junsai" is a type of japanese soup. I did not Know that.
My advice would be to go through the Wook articles for Saber Combat -
https://starwars.fandom.com/wiki/Lightsaber_combat/Legends - and try putting a few different terms together.
Another idea is to use Google Translate to come up with something that sounds good. For example, I used Google Translate to look up the word "deceive" which I decide to use based on your description "strikes from surprising places", and came up with the Hindi "dhokha", the Chinese "Qīpiàn", and Japanese "Azamuku"
