^^ The name "Gilman" has only very recently been added to the camp moc, so it is very doubtful that a search for that term would turn up anything beyond the Rancourt HP.
But, you're right, there has not been much posted here regarding the camp moc. And they do look much more clunky than sleek.
The Rancourt x Taylor Stitch page has a photo of a camp moc that somewhat approximates the shoe you are contemplating (navy x red brick).

I have been emailing back and forth with Rancourt to determine to what extent they can produce a camp moc version of this snuff suede Carmina String Loafer from The Armoury.

I asked about a number of modifications to the standard camp moc to approximate the loafer above, but have yet to hear word back about whether these mods are a possibility. I can let you know if or when I get a response.
1) Blind eyelets
2) Matched stitching
3) Shorter plug
4) A more chiseled last
5) Matched laces
6) "Rolled English Moc" stitching on the toe
