remove cgi Grievous and all battle droids and replace a stop motion models
If the idea is to make it look more realistic, then you’ve failed miserably. Stopmotion is not reliable for realistic VFX. It has a certain charm, but realism is not its strong suit. Of course it can do realism on a hollywood budget, but given no one does it anymore, I suspect it’s become a lot more efficient to do with CGI, and the results are usually just as good.
