Once I understood I had to compile with LMTX, this works like magic ! I spent 
hours to find a solution… but here is a solution ! 
Thanks a lot !

Hi,

I will try again. What if you do

newcircleA := newcircleA scrutinized 2;

after your definition of newcircleA?

but it doesn't add the feature to the current font.
I understand I need a font switch.
Usually I use \switchtobodyfont. How is \definedfont different?
it's a 'permanent' one ... so when the font is loaded the dimensions are 
adapted so you need a new font definition
