Technically yes. But, in practice it doesn't work that well.

Just a quick DOF calculator with some random numbers.

1.6x Factor Crop Sensor
Aperture - f/32
Focal Length - 200mm
Focal Distance - 60inches/5 feet

Nearest Acceptable Sharpness: 58.76in
Furthest Acceptable Sharpness: 61.3in
Total Depth of Field: 2.56in

So, still only a 2.56in area will be sharp, although at F/32 diffraction is going to seriously degrade image quality.
