Paul,
greetings.
I had read with very much interest about Perry's solutions, in your rotary list.
Could we add some  extension in the fan intake, making the correct shape to     > allow the duct to look like your ducted fan with inflatable lips.?

Yes but I don't think I can talk Perry into making yet another duct :-)

Maybe the reverse air flux at static and low speed will decrease, making 
a difference in the flow after the fan.
I think, the drag will not increase substantially at medium speeds and the 
runway take off run and climb ( first climb step) will be better.
Make this any sense???

I don't think reverse flow inside the duct is much of a problem. Perry
has
the clearance down to only 1/8 inch.
