Besides losing your data and having an unlocked bootloader (so bootloader unlocked warning and no safetynet), I don't see any problems since the two builds may be similar. However, I can't be sure, given cross fishing could be risky. I suggest backing up as much as you can before committing. For best stability, you'd likely want to start fresh, full erase, but up to you.
Alternatively, wait for the EU NPNS25.137-93-14 Oreo OTA to be leaked on XDA or other sources. If the Oreo update leads you to the same build as the Indian and Brazil builds (OPS28.85-13) then you could use the EU Oreo OTA to update. I've no idea if VoLTE or other India specific services would work with this approach.
