No Beast Wars in IDW. You know that famous reveal at the end of Beast Wars series 2? Can't happen in the IDW Universe as that crash never happened in IDW.

Instead the Spotlight comic is based on Marvel's origin for Shockwave and the Dinobots with a few Beast Wars touches added (Earth seeded with Energon, CR chambers, the need for the Grimlock and co to wrap themselves in organic beast modes to avoid statis lock).

The G1 Transformers in IDW are on Earth because of the Energon that was planted here by Shockwave. It drives the plot of the first 18 issues or so.

They could do a new take in which case your idea might work but it's unlikely IDW will do anything but make more comics set in the original BW cartoon continuity.
