If you are looking for a ridiculously expensive and difficult project there is a forthcoming 1/72 HP Hastings
http://sandmmodels.co.uk/product/hp-hastings-c1c2/
which could be converted with some difficulty to a Hermes. This was suggested to me by a customer - I inquired if he had not heard of 1/144 scale?
There are a few civilian models in the S+M range. Let me know if you are interested in any as we have an established supply chain due to the HS748.
The Sycamore mentioned on their site is 1/72 injected plastic.
