Maybe not exactly that design, but something like that might work for a rapier combat helm.
East Kingdom Rapier rules say:
3. Head
a. The front and top of the head must be covered by rigid material to below the jaw line and behind the ears. Standard 12 kg fencing masks are known to meet this standard. If built to this standard, fencing helms are also acceptable.
b. The face must be covered by either 12kg mesh (e.g. a standard fencing mask) or perforated metal. Such metal must not have holes larger than 1/8" (3 mm) in diameter, with a minimum offset of 3/16" (5 mm) and shall also meet the definition of rigid material.
c. Masks and helms must be secured so that they cannot be easily removed or dislodged during combat. The combination of snug fit and the spring-tongue in a conventional fencing mask is not sufficient, by itself, to secure the mask to the combatant.
d. Both modern fencing masks and rapier helms shall show no evidence of impending failure (e.g., significant rust or dents, or other defects including spread open mesh, broken weld points, etc). If there is concern about the face mesh of a modern fencing mask, it should be tested using a standard, commercial 12 kg mask punch. Marshals doing the testing must be trained in the use of the punch.
e. The rest of the head must be covered by at least puncture resistant material.
You'd have to have the perforated steel behind and below the oculars, but, some facsimile of a ventail might work to cover everything below the oculars.
Their definition of rigid material is:
c. Rigid Material: Puncture-resistant materials that will not significantly flex, spread apart, or deform under pressure of 12 kg applied repeatedly to any single point. Examples of rigid material are:
22 gauge stainless steel (0.8 mm);
20 gauge mild steel (1.0 mm);
16 gauge aluminum, copper or brass (1.6 mm);
one layer of heavy leather (8 oz., 4 mm).
If not a stand-alone mask/helm combo, then maybe a shell that covers a commercially-made fencing mask. Gerhard's leather rapier helm cover - http://www.lydia.org/bandgun/helm/index.html - isn't bad, but it has a few issues, like the chance of a tip sliding under the visor or between the lobster-tail lames.
I am already in the process of scrapping the crest in it's current form and trying to redesign it so it looks better. This crest has been a pain in the behind, but I am hopeful that the new design will work much better. (But now I will have to go back and trace all of those little lines onto the new pieces. 
) Oh well, ya do what ya gotta do to get it right, I suppose.
)Still lots left to do......
uhhhhhhhh
