That is probably what I might do. I would rather RS Chalk and play Peters in that spot, but you have already RS Peters and it likely does not matter between him and chalk.
I don't like Dickens much .. but better than the other SFs. If you had more Guards, I would agree with zorzil and play Koehler as the starting SF, but with only 4 Guards, I think I would not do that. But I would use Koehler and Harrison as backups at SF>
