The problem with the Intergalactic Com Tower is just because the effect of the wonder is to give a free Communication Satellite in every city. The graphic you see is the Communication Satellite. The Com Tower graphic is there too it's just the fScale needs to be more like 12-14.
The wonders beginning Intergalactic are hopefully going to removed when we redo wonders since they are some of the least thematic and cheesy, but that gold marker graphic is good with a nice animation and can surely be used for something else.
Other comments on the graphics:
The Zensufi reskins are nice.
The Imperial Buildings are pretty good base. I might make some adjustments to the models to give them a Dune twist, add some lions, that kind of thing.
On the Mahdi: I think this religion (together with Shai Hulud) is a less of an establishment religion. Mahdi is about fanatic guerilla militants and I think their buildings should reflect that. It would be cool to have some caves and chambers hewn out of rock for them. Spartan military structures with religous banners, etc, but this will need some custom modelling.
The Qizarate compared to Mahdi *is* an establishment religion so structures like your Dune Messiah shrine or the Dar Al-Hikman (i think that's the Hagia Sofia) are what I envisage for them. Stuff like the pictures I linked to of Arrakeen which is taken from the Children of Dune series set during the Qizarate's most dominant period.
The Shai Hulud ones are good for now. Maybe we'll do something with some worm influences at some point.
The Great Processor is a good choice, but the replacement Hospital is a little bit too ancient looking IMO. I think the Hospital should probably be one of the more sci-fi/furistic buildings. Still it's OK for now.

Unrelated to this, can we use the current Imperial Space Port for the Corrino Palace? It is an icon from the film that people will recognise. I can give it a more reflective gold finish at some point.
