I see, I think you are referring to the hingepin holders? That's what I call them at least. Sounds like a decent idea.

Depending on the vehicle used you could make some wider ones pretty easily, if they are flat pieces stamped or cut out of alum. It's the ones that are more 3-dimensional that could be a challenge (like the RR hingepin holder on my Jammin, has a tab extending forward under the bulkhead).

The only concern I would have is extending those out could really increase the leverage on them when you get in a crash, where they would be more inclined to buckle/fold at the bulkhead.
