no we are talking mods thats the point the dvla only deal with paper work and never come into contact with cars removing part of the inner wing that does nothing is not making the car a hybrid there conserne is people having a spaceframed car with a crazy engine and custom floor pan and a mini outer skin on top thats a hybrid car again this still comes down to your personal opinion and dislike of the mod theres no need to go on about it when you might not be right and the area of the inner wing left is a fair bit more that 50%
the DVLA are responsible for the licensing of vehicles, just check who you have to send your V5 to for changes
if you loose the identity of your mini it's no longer a mini, what you have made is a hybrid between a mini and the bit you added to it
it is not a full on kit car where you change the body but still use a donor body
