Yup. Julia was alongside Wanda in the supporting cast of the IRON MAN cartoon. They might even have been called "Force Works"
And my recollection of the progression of that version of Wanda's battle dress was that it was introduced in the SCARLET WITCH miniseries which occurred during the end days of the AVENGERS WEST COAST series, which transitioned to FORCE WORKS, where she indeed wore the dress until returning to the official AVENGERS fold with THE CROSSING. So since the WITCH mini was written by Abnett/Lanning, as was WORKS, but there is no continuity of visual artist, it's likely from their direction for a new look...or someone editorially higher up.
