I'm a Transformer collector with a few non-transformer items in my collection. Two of which are a DC Universe Classics Martian Manhunter and a DC Multiverse Jon Stewart Green Lantern. I'm hoping to find a way to recreate a poster from my childhood of the 2001 Justice League cartoon main 7 (see attached) in toy form.

I'm inclined to go with 6"/7" figures, since I already have two. The trouble is that would take up a little more room than I'd like, but it would mean more posing options and accessories. I've been looking at the old JLU 3-3/4" figures, and they certainly look appealing. I just can't find a good place to buy them in my area (near Toronto, Ontario Canada).

Any recommendations on what to buy and where to get it?
