But here's the thing: I've stated my clear preference for the 3940 versus the 5140. I feel that the relative proportions of the case size and subdial letterings for the 3940 work better than the 5140 (photo from Mech at PuristSpro):
I think the larger letterings work for the 5040 (which I have too), but because of the unique tonneau shape:

But what really comes across as a bit "off" to me about the 5140 is that squished up "27" in the date/moonphase subdial:
Which, interestingly enough, does NOT show up in the 5136/1J, despite the smaller case size (36/37mm versus the 5140's 39mm) and the larger letters in the other subdials:
I know I may be acting a bit unnecessarily nitpicky about this, and if someone wants to give me a 5140P for free I'm happy to own it.
Just wanted to share my nitpicky thoughts with you folks.
IMHO each of those pieces is beautiful and their respective dials/fonts work well for each of them. Whenever a company puts a movement from a smaller watch into a larger case they have to do something to compensate and the subdials or date windows etc from looking like they are set too close to the center of the watch. Hence, sometimes hour markers get larger as they do at the 3 & 9 on the 5140 (compared to the smaller markers at 3& 9 on the 3940). I think if they had stuck with smaller font it would have seemed out of proportion to the new larger case and dial, and then it might create a somewhat stark or barren looking dial.
I agree the Tonneau case seems ideally suited for larger font. Its a very unusual case, especially for Patek. I more commonly see that case shape (or variety of case shapes associated with VC and Cartier). While the Tonneau is still dressy, I find its a bit more relaxed and whimsical than the expected round Patek. I think its a case shape that is very under appreciated and I admire your choice of going with something thats so different from their signature round cases.
As for the squished 5 and 27, I can understand your not liking it. Although, I think they handled it quite well, and IMHO its much nicer looking than when they cut out part of a number on the 5059. Just my 2 cents. Always great seeing photos of your perpetual calendars.
