The short answer is, yes, but if you are very familiar with keeping bonzai trees then this can be done. The roots will require constant maintenance, and trimming... But very properly. These trees are about 30 feet tall in nature, so keeping them 1/30th of that height will be very difficult. They also don't trim as well as their close relative, the Leyland Cypress. I would suggest crawling junipers. They will be more tolerant of confined spaces, and often won't exceed 2 feet in height.
