LITS Construction and Nanro Construction

I had initially set out to design a Nanro Construction when the same idea around the LITS puzzle struck me. I admit I have enjoyed 'constructing' Nanro Construction puzzles more than the LITS ones though. To the best of my knowledge, these are novel ideas that were not explored to date. Now the rules:

The given grid contains even number of outlined areas, each of which has to amalgamate with one adjoining area. When you have got all areas correct, the result is a standard LITS (or Nanro) puzzle that is uniquely solvable.
