Unfortunately, Anki cannot randomly pick from a list of conjugations. So you would have to make individual cards for each conjugation. You could make a deck like this by importing your barrons list into excel and copying the dictionary version for each conjugation. Then you would need to manually add all of the conjugations using something like http://www.japaneseverbconjugator.com. Export your spreadsheet as a csv file and import into anki. This seems like a lot of work though. It would probably be a lot easier to just learn the conjugation rules.
