gasgas wheels set

Is there a crossover for 09-10 gasgas 250ec wheels or aftermaket wheels for gasgas bikes?

I would think the 09 and 10 are the same as the earlier GasGas wheels since 99-07 are the same. Bearings and spacers do differ somewhat from earlier to later gassers but the hubs are the same. You could change out bearings and spacers on other wheels to make them fit your bike as long as the sprocket and brake disk attach the same distance from the center of the wheel as on the wheel you're replacing. A friend has a kawasaki wheel on the back of his 300.
If you're talking just about the rims your options are very limited because GasGas laces up their wheels differently than the big 5 companies do. Every 3rd or 4th nipple is aimed in the opposite direction compared to the big 5. Husaberg or Husky may use the same lacing pattern but I don't know which.
