These Strelets travellers look brilliant (with your usual great painting), and I'm sure you'll be able to come up with some great scenarios and uses for them.
I'm very tempted to pick some up myself to add to the pile!
It looks as though the frosting only affected the base, so maybe you can paint over it again. The one time I had serious frosting problems on some miniatures (sprayed varnish too much and too close), I followed some advice on the internet and rubbed olive oil into the frosting with a cotton bud. This went quite a long way towards rescuing the paint jobs, and I've always been much more careful since then when varnishing.
