Imo, ramming for damage doesn't really work in SS.
What happens when you succeed at killing the target ship with a ram? - It explodes and takes you out at as well!
And if you have something like spike long enough to kill enemy from outside their explosion radius, it's about 450 or so, same as shorter range weapons already in game.
Though yeah, to some degree you can do it with Odyssey. Use system to rush at enemy and activate shield at distance where your hull is still outside their shield, but your shield is inside their hull (so, you can only do it to smaller ships).
