Need help (movie knowledgable people)

I am trying to collect one figure of everyone from the series. I just bought a Voyager Blackout. I want them to match up as size wise as I can. Can you help me make a list of figs I need to buy to do that?
I am thinking.
Deluxe
Barricade
Brawl
Bumblebee
Jazz
Bonecrusher
Voyagers
Blackout
Ratchet
Ironhide
Starscream
Optimus Prime
Megatron
If I buy all these figs, will they be in scale with one another? I mean, will they be the right size, as I know Blackout should be a lot bigger than Jazz, ect.
If not, can you kindly move them around, or list some other figs that I should get that would work better? Thanks.
