switch without base?

[RussNelson]

I want to make a one-handed chording keyboard using these switches. They need to be at slight angles to each other to reflect the angle of movement of the fingers. When relaxed the fingers as slightly separated but when you pull them in, they get closer. That's part of the angle that needs to be different for each switch. They also need to be closer together than they would be using the body.

Has anybody come up with a modification that cuts just the hole for the sheath, so I can create a multi-switch body by cutting multiple holes at the correct orientation?
