So net net, I would guess that it would today be a top 5-ish or even top 3-ish.
Obviously this is 110% speculation and none of us know...which makes the question even better.
Yes, it's all a matter of opinion, but I do not think your estimate is very likely at all.
First of all, when Lido was named one of the top three courses in America, it was 1926. Courses like Cypress Point and Pebble Beach [in its present form] did not yet exist. There's a lot more competition than there was.
I feel certain that Lido got some of its stature from its setting between Reynolds Channel and the Atlantic Ocean, which lapped at the edge of the Biarritz 8th hole. But long before the course ceased to exist, part of the 8th hole was washed away, and the seafront was taken up by beach cabanas. Also, if the course still existed today, the traffic through the middle of the course would be a much bigger negative than it was in 1926.
The third and last point is that the holes were built very close together -- too close for today's game. Our intent is to reproduce the course as exactly as we can in Wisconsin, but we have to space the holes further apart for safety. Just to cite one example, the 15th green, 16th tee, 10th green, and 11th tee were all in play to either side of the par-5 17th. If we built it exactly as it had been, I'd get sued the first month the course was open.
The original Lido did not have more acreage available to fix that problem, or to lengthen any of its holes to keep up with modern equipment. It would still be 6400 yards on 115 acres, with a busy road you had to hit across four times. Top five? I don't think so.
Luckily, most of the problems in that last paragraph can be easily addressed in Wisconsin, but we still don't have an ocean setting to our advantage. Where will it be ranked? I don't really care; I just want to build it as faithfully as the lawyers will let me.
