Is the PowerBlow worth it without SLR?

I’m thinking about getting the powerblow to use with my keon. So far I haven’t been using SLR as I’m not a fan of the subscription model so I’ve been getting my scripts from here and using scriptplayer.
From the looks of it the only site to make use of the powerblow is SLR and it seems like it wouldn’t be worth getting it without SLR.

-Side note if it isn’t would it be possible to trigger it if the Keon is positioned lower for some time? idk just a thought.
