Covering chocolate cake with roll out fondant

Eire76

I am making Mary Berry's Chocolate Sponge cake for my dd birthday at the weekend, ingredients as follows, I can't post a link as I am a new user:

Sponge
50g/2oz cocoa powder
6 tbsp boiling water
3 free-range eggs
4 tbsp milk
175g/6oz self-raising flour
1 rounded tsp baking powder
100g/4oz baking spread or soft butter
300g/10oz natural caster sugar

Ganache to be spread between layers and over the whole cake.

I have made the cake a couple of times before, once with the chocolate ganache and then covered that with butter icing. This time I hope to use the roll out fondant, my 2 questions are:
1. Is it ok to put the Roll out fondant straight onto the Ganache or should I leave the Ganache out this time?

2. Will the Roll out Fondant be too heavy for this type of cake?

Thanks in advance.

Roll out sugarpaste will be fine over the ganache, put on a good layer which will strengthen the cake for under the icing, will be fine.
