Assuming you're keeping the original dial, the crown location will be at 12 o'clock. Short, wide lugs would work, similar to the original holder. If you look at other Chopard LUC cases from the era where these hands were the signature, you can see the lugs were typically thick and squat.
You could consider doing a driver's style watch, where the watch face is rotated, similar to the Vacheron Historiques 1921. Moving the crown away from the lugs will open up more possibilities in terms of lug designs, and a driver's style watch is consistent with Chopard's ties to motorsports.
If you're changing the dial, so the crown is not at 12 o'clock, you could go for an RGM style case, with the lugs turned downward to allow the strap to fit a modest wrist.
