Will I run into any problems using Seed_It and Sphere2 together?

I know that Seed_It requires you to attach the generated script to the terrain, but I am not sure about Sphere.

Also, will both of these add-ons work fine in A7? I am pretty confident that Seed_It will, but I have read in a few places that Sphere2 was written for A6.5/6 which is what causes my concern.

Thanks,
