Something like this:

body {
   font-size: 1em; /* to have a consistent font-size for all ebook */
}

p {
   margin: 0;
   text-align: justify;
   text-indent: 1.2em;
   line-height: 1.2em;
   font-size: 100%; /* now that 100% is 100% of font-size of body */
}

p.drop {
   text-indent: 0;
}

.dropCap {
   float: left;
   line-height: 1.2em;
   font-size: 360%; /* Or the size you wish */
   font-weight: bold;
   margin: -0.02em 5px -0.03em 0; /* Here you could need change these values */
}

The best output under .kf8 is by employing a .svg image, so what floats as drop cap is not a letter but an image. Best (perfect) output for drop caps (no matter the font-size) is achieved under KFX and under epub3 with ereaders that suppor "initial-letter" (or "-webkit-initial-letter") property. In my tests with epub3 all Sigil's plugins, Calibre Viewer, Thorium, Koodo Reader, Foliate, Cantook, Reasily, Lithium, PocketBook, Infinity Reader and Kobo for Android support that property.

The line-height of 1.2em might not work on a Kindle in KFX. Also, you don't want to force a line height as one of the reasons for using ChareInk6SP is to have a smaller line height and if your line-height works, then it spoils the line height of the font. So can you do a dropcap in KFX without the line-height and not knowing what the default line-height will be?
