Interesting take. I think ebikes are great, but I've never once thought they should be raced. At that point it would be better to just do motorcycle racing so you can be properly equipped for crashes occurring at high speeds. Cycling races already have enough crashes as it is, and that is before you take an equalizer that allows less experienced riders to ride faster and in situations where they need to be able to ride in a pack without overlapping wheels and occasionally rubbing shoulders/ elbows.
Otoh, if the horse scene has room for hobby horses who am i to say cycling races can't have ebike categories? (I'm joking, hobby horses doesn't hurt anyone and ebike racing would have higher % chance of accidents than traditional races. Guaranteed).
For 3k pounds.... id rather go to a wind tunnel
Ps you can test aerodynamics with golden cheetah's aerolab if you take accurate weather measurements. Its not going to be as accurate as a wind tunnel but it can help with positions or different kits.
