An author I am working with requires typesettng of their work as follows, but the Russian letters used in some of the drop caps overlap the 4th line. I tried plaing as per the comments in the below MWE, but could not go below the height achieved by its current state. How can I reduce the drop cap font size a little bit to remove the slight overlap?

memoir has integrated lettrine package. it can be used in text for example as versalДlipsum[66] which gives the same result as lettrine[]Д from letttrine package.

a dirty hack, which lift letters in versal for small amount, is:

I'd use loversize=-0.1 and a positive value to lraise.
