Mecanum Wheel Considerations

[OWD]

Hello all, I've been talking with everyone on my team concerning a design that team 1322 had on their site (I'd like to thank them for posting it!). Concerning the mecanum wheel designs they have, one of their thoughts has a mecanum wheels on opposing corners (say, front left and rear right) with regular wheels for the other. I believe the purpose of the design is simply to help in turning, since the mecanum wheels would project a force closer to the direction they would want to turn in.

Will this design climb ramps? Will it require any other special programming? We won't be moving sideways, but the wheels are different. If their design is too complex, my team may drop the idea of powered mecanum, and use them passively as rear wheels.

Please help!
