If it's just one hand selected, I need to sit to the left of two guys calling games without blinds

hold 'em obvi.

no, I don't think so.

When we play dealers choice, it's either dealer ante (aka button ante) or we pay blinds for ALL games, including the stud games. Even the guys that don't notice paired and flushed boards knew that wasn't kosher

You can bring it up, but don't talk about positional advantage. Just say you want it to go a full orbit so people can "get a feel for the game" before it changes right away. I bet you get some people to agree with you.
