Hi Chris
Just ignore the very ignorant reply of the last post
Have a good old read Enoch's build blog ( A very much missed former builder )
http://www.deepfolly.co.uk/index.html
A darn good read.
Enoch raised the height of his scuttle to gain some extra clearance.
If you ask me, Enoch's build turned out well & not at all out of proportion
I know it's not exactly as per your proposal but it may give you some inspiration.
Dare say with a little bit of creative bodywork, anything is possible
