Yeah maybe,
But it really depends on where the wheels are hitting, pull one of them and look to see where the contact is. If the contact is straight in toward the direction of the hub then the 5mm spacer would give you a full 5mm of space, if on the other hand the wheel was rubbing on the curve or the wheel at a 45° angle then it would only give you 2.5 which may or may not be enough, if on the other hand its hitting the outside of a brake caliper you may need to pull the wheel outwards 15mm or more to achieve adequate clearance....Sorry for the complicated answer but you just can't cheat physics
