J-L70+ Z435- is Big Y worth it?

Trying to decide if a Big Y will give much usable info when sequence is J-L70+ and Z435- (and other standard downstream markers negative). The STRs are pretty rare (at 12 markers, only people in whole FTDNA database that match are others with same surname and beyond 12, the two lines of this surname do not match each other at the 25 marker level.) I am assuming all are J-L70 though only one tested. So the big Y would presumably give some snps that allow one to go beyond L70* place currently stuck at - but its not clear i could do anything with that info. I suppose if there is a registry somewhere of all the unique snps for those that are L70* not yet officially recognized, I could then see if we have any of those, even if the STRs are very different. I'm not immersed in the Big Y culture though, so don't even know if such a database exists, apart from what one can piece together by looking at projects where sometimes the headers and other results pages contain the info. Seems maybe like alot of work for very small odds of a payoff? But not sure, so curious what others think. Thanks.
