Well, thanks for the advice, but we are not in the UK and I do not like to experiment with "orphans" types. In France there was once a great idea , put the wings of a DR400-180 on a sleeker one person cell to reduce weight and drag, and add the engine and the landing gear of a Rallye 180 , it was built especially for towing , called a MIDOUR .
look here :

It climbs like a rocket, but it is not certified. And it is only good for towing, nothing else.
We were looking for an all rounder a bit stronger and faster than our PA18 ( which still does an fantastic job at low costs.)
