I think q1 and q2 have the same answer. (although I haven't seen Voyager Prime irl.)
To create a nice cast...

Leader Megs
Leader Bulkhead
Voyager Prime
Voyager Starscream
Deluxe BA
Activator BB (I don't care after seeing Kyle's pics. Activator BB looks perfect))
Deluxe Prowl
Deluxe Ratchet
Deluxe Lockdown
