Let's Put this Battle of Britain thing in Historical Context..

[JG3_Hartmann]

Well I don't think the Royal Navy would have been a real thread for a German invasion fleet. There would have been no better present for Hitler and the Luftwaffe than having the Home Fleet doing a parade in the Channel. Every German plane which could carry even something similar like a weapon would have been used for the attack on the capital ships...and if they would have used only small vessels...well they wouldn't have been able to do much against an invasion.
