Short and simple: No. Custom views are merely meant for 3D navigation.
Wasn't there a script someplace that created a new camera to correspond to one of the custom views? Gerard would know, of course, but you can search the expressions and scripting support forums.
The custom views in AE are orthographic projections rather than perspective views. You can simulate this with a very long lens on your camera.
Try this. Add a new camera to your scene setting the focal length to 10000mm. Add a 3D null to your scene. Make the null the parent of the camera. Rotate the null to x 45º, y 35º and Z 31º and you'll have a fairly good approximation of the default Custom View 1. The very long focal length minimizes the perspective distortion of the scene. It also makes the camera very difficult to manipulate. That's the reason for the null.
The long lens approximates ortho views because perspective is controlled by camera position and, technically, an orthographic view is a view from a camera at an infinite distance from the subject. Sub pixel rasterization becomes a little funky at very long focal lengths so make sure that all of your layers have Collapse Transformations turned on.
bogiesan - thanks for the vote of confidence, but no script required.
Keep in mind, this will unfortunately create problems with 3D model textures popping in element 3D. The further the camera is from your subject, the more difficult time it has in deciphering which surface is in front of the other.
