This is less a recommendation and more of a, I don't think this will work for you even if modified, post. I've been using a Rocky Mounts Backstage swing away since last summer and it works for my needs but I don't think it could handle two 65lb E Bikes. Especially if you added an extension to clear the Aluminess goodies. Not to mention if you go off road with it. Normally my bike on the rack weighs around 50lbs as I will remove the battery, rear bag, and seat while on the rack. With my bike and another regular mountain bike it seems to be at the limit of what the Backstage can handle. When going off road I'll put ratchet straps down to the bumper for stability and if it's really, really rough I'll fold my bike and just put it in the van.
Just wanted to perhaps save you some time if you were considering the Rocky Mounts Backstage. For what your looking for I think you need something stronger. It's a very nice, sturdy rack and compared to some not quite as expensive for a swing away.
BrianW brings up a good point as my rack is about as high as I want to lift my heavy E Bike. Especially if I'm tired. What doesn't help is the Backstage has small tire trays that you need to land the bike on while holding it at shoulder height. Well, my shoulder height.
Good luck on your search

The square tail lights do not come with the rack. I added those to help "friendly" Colorado drivers. Also in the pictures the second bike tray isn't there but you do get two.
