tristate picaxe

A thought for using the tristate capability of (some) picaxe pins

After reading Nuumio's tip, and reading some of the efforts by oddbot, nuumio and ignoblegnome, I was wondering if is possible to take advantage of the tristate config of the picaxe pins using only one transistor for each pin. I was really just trying to reduce the component count.. or more usefully, the SIZE of the board and it's cost.
