Once the lobster is synthesised, it will be possible to synthesise arbitrarily large c/7 diagonal spaceships by incrementally attaching wing pushalongs. Here's a method of attaching the first pushalong:
Code: Select all
x = 51, y = 64, rule = B3/S23

The subsequent pushalongs are easier to attach because the other wing of the lobster doesn't get in the way:
Code: Select all
x = 195, y = 76, rule = B3/S23

Possibly useful predecessor for a variant of the red cells in TigerCub414's post above:
Code: Select all

Edit: I found a way of attaching the "tubber" tagalong:

It's also possible to attach this tagalong to every pushalong in a chain:
