If you do decide to undertake a swerve/crab design make sure to spend a little extra time in the design process to build in a back up plan; Make you can switch the crab/swerve into just a normal 4WD in case it doesn't work out. This way you at least have a driving base in case of failure and won't be stuck with a completely disappointing season.

I'd say go for it if you have you have a reasonable amount of resources; you miss 100% of the shots you don't take.
