Yep. Keep objectives as it is but make the walls look cooler, add more graphics for different percentages of damaged walls.
Update guards from base skins possibly to something thematic. Make lords bigger, and maybe less humanoid model, so people can click them easier for HP and tell apart from players. My opinion is that the skills can stay the same and simple but things like lord horn should have better tells. Maybe make Ogrewatch have actual Ogre models for guards and Quentin Hyleks, etc. But with simple skills, none of that desert bl evade/block pointless stuff. You can also design towers with the races architecture. Skritt architecture tower, or a dredge one with massive gong above lords room that rings whenever the tower flips (EotM flashbacks, heh).
We know there aren't many, if any, WvW devs, but at least the PvE graphic lads should be able to do this for us.
Riformed - Back but playing casually
