If you are thinking about replacing the drives, I'd go with Geckos. They are bipolar, but you can set use your 6-wire motors in series or half-winding configuration. Do you know your motor's rated current and voltage (not supply voltage, winding voltage, determined by multiplying the rated winding current by the winding resistance).
