I wouldn't.
I don't know what a ski-doo weighs, but if it's anything like a sea-doo, you're looking at at least 500-600 lbs apiece and then about another 150-350 for the trailer. That's 1100-1600 lbs.
The problem isn't necessarily power (although of course that will be a concern) but braking ability. You'd be increasing the weight of the car by about 50% which is pretty substantial. Also, being a relatively small car, you'd run the risk of the trailer doing some of the steering for you - which also isn't the greatest feeling in the world.
I'd venture that you could probably tow a single one without incident, but two would be pushing the limits of sanity. (I've towed single and double jetskis before, and the single was no big deal but the doubles definitely were a noticable load)
