Questions on John Meadows' Gamma Bomb: Alternatives with minimal equipment

So I decided to run Gamma Bomb, however I don't have a decent chunk of the prescribed equipment. I know it's not optimal, but am I completely destroying the program?

Dumbbell Press -> Barbell Press (My dumbbells only go up to 30lbs)

Decline bench leg raises -> Hanging leg raises

Machine Press -> Barbell Press

Machine fly -> Dumbbell Fly

Machine rear delts/reverse pec deck -> Uhh... DB rear delt flyes?

Lying leg curl -> I have no idea. RDLs?

Leg Press -> Barbell Squats

Flat dumbbell press -> Barbell bench

Machine side laterals -> DB laterals

Obviously John knows better than me, but work with what you have, right?
