Basically, you need to get the XML for the action you want to mangle (Set Clipboard to Styled Text) and adjust the text of the named clipboard within the action and then execute the XML as an action using AppleScript.

You can get the XML for the action from the Gear menu Copy as XML.

Then you need to adjust the XML for the StyledText to match %NamedClipboard%WHATEVER%, and then run the XML using the AppleScript:

tell application "Keyboard Maestro Engine"
	set v to getvariable "ActionXML"
	do script v
end tell

Unfortunately, for your purposes, to use the Styled Text, you need to adjust the StyledText field, and while that is doable, it is difficult as well. @JMichaelTX has a script for doing it here:

But it is tricky to put it all together.
