I have. I made 1/4" hardware cloth tubes that fit the Little Giant turner rails so that I could incubate oversize turkey eggs (one was 152g). The eggs laid end to end along the rail, and I used zip ties to secure the wire to the plastic rail. The huge egg was twins, and they developed side by side, with plenty of room. They made it to 21 days, when one quit, and the other followed soon after.
I've considered creating some for the GQF that will fit in the existing metal trays. I'd run them front to rear so they will roll over a 90 degree arc instead of tipping over a 90 degree arc.
