Have you tried APA league rules? They don't allow dedicated jump cues, so you would have to use your playing cue to attempt jump shots.
Specialty Cues – Specialty Cues are cues specially tailored to perform specific shots. These include, but are not limited to, jump cues, break cues, and jump-break cues (combination of jump cues and break cues).

Up to a quarter million play in weekly leagues, you may be able to find someone like minded.

I have one, and will use it as needed. I don't love jump shots, but since they are a legal I'll use them.
I wish rule sets were that you can only jump with a full cue.
