Hi and welcome bro to our community Sadly it wouldn't work cant see how without SERIOUS work fabricating it and even at that getting it to look right seriously it would look naff the difference between a lwb and swb is only 14cm ??? so that wouldnt work either im afraid its all or nothing
What possibly could be acheived is the sunroof left in place with the pop over the top so when the pop top is up you can open the sunroof for air maybe as all leave a chunk of the roof above the cab intact, not entirely sure but it may work
