Adjusting Vertical metrics – Interlign problem

I first drew these letters as lowercase (height of 500), and i want them to be the uppercase for the typeface. I tried to simply adjust the vertical metrics (see screenshot), but it seems to be a trouble when i compose some text in Indesign, the automatic space between lines is unusually too big (see screenshot).
Is there a way to fix this – without rescaling everything with a 700 letter height ?

Thank you !

In File > Font Info > Font, lower the number for UPM (Units per Em), e.g. to 700
