I don't know what exactly your application is, but split grounds... it's rarely recommended these days. I'm surprised nobody commented on this yet.
Of course you may have very good reasons for doing so, but as you yourself noted, they are often best avoided. So I'm curious what your rationale is here for choosing this approach.
As a general thought, split grounds typically between "digital" and "analog" sections is *usually* NOT a good idea, and further putting inductors between them makes things worse.
Your design looks a bit different, as if I understand correctly, you essentially have a very noisy, power section, and a cleaner section. Rather than split grounds, if you really do not manage to keep noise under control for the "clean" section using a common ground, something that may be more sensible could be to galvanically isolate the two sides completely. Just a thought.
