I can't ever see this getting an EASA STC.
(1) The cost of proving it
(2) One of the reasons that RHC didn't put a V14 onto the nose of an R44 is because the V14 (when powered down) drops its snout and creates a "tripping" problem in EOL over water. They tested that and realised it was a danger.
(3) They never certified the 44 ENG (V12) with floats, for a similar reason.
(4) Hanging a V14 off the nose of an R44 is "like hanging one of my kids off it" according to Kurt Robinson. W&B becomes a real problem.
Skid height/ground clearance on the 66 isn't any better.
