How do you solve a problem like Battle Sister Maria?

So these sisters have been sitting in a box for a long long time  at my folks place in storage.

I didn't paint them

I don't actually own them


But they are at my house and the owner doesn't want them anymore. So I guess ill keep them.

Long story short they were a friends army who played a small bit but got a lot of models, he gave up the hobby and gave all his stuff away. We all forgot I had them so they stayed in a box for nearly a decade.


So, I reckon I should resurrect them and give them a new lease on life. 

The first thing to note is that they aren't well painted.

Actually, its a pretty ordinary job if you don't mind me saying. This is from a guy who claimed to be a GW store guy and an expert painter. He charged good money for this paint job.

I would be stunned if any GW trained person turned in a job like this.

So, what to do?

Should i keep them as is and use them as a reserve army?

Should i retouch the paint scheme, try and give it some more detail and depth?

Should I strip them back and repaint them in a new scheme?

Chances are, it will be the latter

Using the handy dandy sisters of battle painter on bolter and chainsword I came up with he following first idea for a new scheme.

Any thoughts and feedback on this would be appreciated. 

Of course, megapope will be super glad to point out i'm suggesting a blue paint scheme. As though painting a model blue is a virtue of it's own.
