According to the Perry's site, the figures are 1-piece sculpts, except for the sword arm--so no, the pelisse is not a 'separate' glue-on item. You would have to carve it off, and repair the dolman with greenstuff, in order to convert to your requirement. There are, however, Austrian Hussars offered in 'campaign' look, wearing the pelisse (rather than with it 'slung' over the shoulders).
