Gang:
Setting a line-height at 120% or 1.2ems is not worth doing, as that's the default setting for all Kindles, anyway. You can't change it to 100% or 1.0em.
ALSO, on real devices, most Raised Initials will cause the line-spacing of which we're speaking; while you can sometimes get it to look "right" on Previewer, it still shows the extra leading between the first and second lines on devices. On Paperwhite, which is even more "font-sensitive" than almost all the others, this is pretty much a lost cause, as something like 98% of the readers never know to turn on "Publisher Font," (which they MUST do to get the embedded font, mind you), ANYWAY.
The user doesn't have to 'select a different font;" in order to see all the work you've done, they have to actively go to "Fonts-->Publisher Font" in order to see what you did in the FIRST place. Unlike other Kindles, they don't default-display the embedded font--you have to turn it ON.
So, while I'm all for embellishing books as the next guy, remember that the vast majority of PPW readers will never see an embedded font, much less the Initial Cap, DropCap, or anything else that you've labored to put in there. Trust me: I spent a lot of time coming to grips with that little bit of reality, myself.
FWIW.

For all intents and purposes,
YES.
You may as well.

What's your media-query/fallback styling for the K7's, for that svg?
