Drop Cap Style - remove and preserve formatting, find and replace others using same

Hiya,

I've written the below code to "flatten" (I'm more a Photoshop guy, so that makes more sense to me as a term) nested styles, and find and replace any other text using the same nested styles. 
I'd like to do the same for Drop Cap Styles but am a bit of a loss where to start. There are no corresponding textPreferences for Drop Caps so that's out, beyond that I'm lost. 

Any pointers would be greatly appreciated,
Tim

    function removeStyles(check, whitelist) {
        for (i = doc.allParagraphStyles.length - 1; i >= 0; i--) {
            var clientItem = whitelist[3].arr[i];
            var hostItem = doc.allParagraphStyles[i];
            try {
                if (clientItem.checked === check && clientItem.name === hostItem.name) {
                    applyNestedStyles(hostItem, hostItem.nestedStyles);
                    applyNestedStyles(hostItem, hostItem.nestedLineStyles);
                    hostItem.dropCapStyle.remove();
                    hostItem.remove();
                }
            }
            catch (e) {
            }

            app.findTextPreferences.appliedCharacterStyle = charStyle;

            doc.changeText();
        }
