Gökay, Short answer is no; you cannot use large double-precision coordinates directly because the hardware will not support them without a loss of precision.
You will need to find a local origin, put that in a Transform, and re-write the geometry verts relative to that local origin. It sounds like you are already trying to do that. If the data covers too large an area though, your only option is to split it up into pieces and transform each piece to its own local origin under its own Transform.
