Simple 3D design required

I need some help with 3D design of the wireless charger station. I want to see how this charger will look in a squarish shape, currently it is round. I dont need a design from scratch, Just need a modified version of existing design. I have attached photos of the existing design.

Please note points below:
1) change the shape of outer arc to square. Currently it is round. Note the arc has a light.
2) change the shape of center base (grey clot) to square. Current shape is oval/semi-circular.
3) i don’t change or the overall dimensions of the charger. Size is 220x179x193 (H).

I have tried to make a very rough sketch with red lines (photo attached). It is not great but gives an idea of what I am looking for.

Please send your proposals with examples of any products you have designed in the past.

Thanks
