I think it would be hard to get all the required fragments without raising red flags. There aren't that many synthesis companies and it would take a lot of fragments. Assuming you could get the fragments, its getting easier to assemble (join) them quickly. A 40000 base pair T7 bacteriophage genome was recently assembled from 52 parts in a single reaction (one tube)!
