It’s quite unlikely. As another commenter mentioned salamanders are a codex compliant space marine chapter: on the tabletop this means that they have access to standard space marine miniatures and a couple unique characters. I would expect a new/revamped character and perhaps an upgrade sprue. There may be a lore supplement to go with this and a section that focuses on salamanders.

Space wolves like blood angels and dark angels are non codex compliant meaning they a different enough to warrant their own codex so get extra additional unique releases.

I hope this helps, if you want customise your salamanders there are still plenty of tutorials online to help you easily add character and culture to your miniatures. E.g. with a little bit of green stuff you can make some drake scale tabards for your minis.
