The Only Problem You face is with text and styles
IMO simon.
Just an Idea, Don't Try This Styles And Keep away from Actions For sometime, Not for a while.
You should manually Go through the Blending options and Keep The Good Parts up Which match the text and the sig. With this, The Text Gets Gently Blended Into the Sig.
Now, Coming Upon the Text, If you just Don't get an Idea on what to do with the text and which text to choose OR You Might have got sticked with the fonts which you generally Used for sigs,
Just Sit'e and Relax, Think how the text should be like On the sigs..Then, Go through the List Of fonts and select the matching of your imagination.
, ..With Hope:upray this Might work's'le for you.
Yours Sincerely,
