Canon speedlites are a pain to use with anything but other Canon speedlites... how are you triggering the lights? If you are trying to slave them off the Bowens they will almost certainlty not work (some oddity of the way that Canon slave system works), they also don't work with standard IR triggers. If you are usinging radio triggers on all of the flashes then they should work. If you are firing a single flash using a PC sync lead (or a wireless trigger) then it might work if you fire the Canon and slave the others off it. Also make sure that you have them set to high speed flash sync or that could also cause problems.
