Given the curves of the face, there's only so long before a blade becomes useless - most straights are (folks that shave with straights can correct me if I'm wildly wrong here) between three and four inches long, given heel to nose I'd say most are about three inches long (about 8cm).
Probably the closest to that length (from the shavettes that I've used) is the Dovo and/or Burmax which uses a very similar blade. The Dovo is well regarded, but blade choice is very limited. Shorter, and you're down to Artist Club and Personna shaper blade lengths ... quick measure, it's two and quarter inches (almost 6cm) on the Personna shaper blades. I don't like AC and so don't have any in, but they're about the same length. DE blades are one and half inches (4cm).
Here's the Dovo:
... where actually, you can see that the blade is about twice the length of a DE and actually kinda looks like two DEs next to each other (without the deadly gap). This is closest to what you're describing. As above, you can get inserts (see the red bit?) to hold DE blades (black insert) and even Personna shaper blades (green insert).
Your choice of long blades is ...
One. Dovo. If you don't like 'em you're stuffed
