I need the help of the community.  I am trying to find an efficient way to make veterans.  I was thinking of painting normal praetorian models in a different scheme.  My considerations are 91st Highlanders or Mounted Infantry.

Ignore the fact that the infantry is on horseback, I am just curious about the color scheme.

The rest of my army is going to be painted similar to Col.Gravis.  There is a picture of my test model in an earlier post.  Do you all think would work, or should I look at trying to do some kind of conversion?  I have enough of the regular models to make this a simple and inexpensive option.  Please give me your input.  I look forward to it.
