The easiest way is to redesign the current EF mount lens as RF mount lens, by making the barrels longer in place of an adaptor, resulting in a collection of lens that is slightly longer and heavier.

Those would still be EF-lenses, just with a build in adapter. I can't see any reason at all to buy such a lens. They are less capable than EF-lenses. You can't use control-ring-adapters or filter-adapters for example and you can't use them on EF-bodies. They are totally pointless.

The main challenge for Sigma and Tamron is to re-engineer the RF-protocol. This could not be done in a few month. It will take years.
