The major issue with something like this is that no one really have the option to look into IPS, and how it does it stuff, unless they pay the price for a license...
If IPS is extendable/modular with it's banlist, or otherwise easily possible to access other databases, then or holds other things like e.g. something similar forwards/natives in SourceMod plugins, it would probably easily be possible to (also check) the SourceBans database.
But otherwise, if the IPS database is simple, you can make a cron job that runs every 5 minutes or so, which will SELECT your bans from SouceBans, then INSERT into the ban table on IPS.

To be honest, I'm not surprised.
It would be more likely to see such things as "already available" for FOSS ("Free and open-source software") things, where everyone can participate without giving a single penny, than it would on limited access systems like e.g. IPS, XenForo, and others...
However, with a FOSS system (e.g. phpBB), which I can easily peek into the source code, without spending a single penny, there it would likely be beneficial for many other people too.
a) So beneficial just for you (who have paid/wants to pay/are able to pay for the board)?
b) Beneficial for many people at a time (including people who might not be able to afford those kind of licenses)?
There I would personally prioritize spending time on the FOSS and B) combo.
