If you truly want a 2 or 3 hander from a top tier brand, then hold out for it. It will be well worth it! But yes, temptation is all around and can make it tough to get to our goal without distractions.
The GP Traveler is very nice, but I have to go with RNguy, even though its a common design feature the short hands bother me a bit, be it on a GP or the Patek. As you currently have the dual time, I realize its not a world time watch, but still it will do the job...I would avoid the GP and other distractions and focus on a 2 or 3 hand top tier brand as that seems to be something your don't currently have.
For me, I just don't know what direction I want to move in for my next piece. I have a few top tier dress watches, I have an AP RO luxury sport watch, and I have sportier watches such as Daytonas, Ex 2, and Sub. So for me its not really a matter of filling in a gap in my collection. I hope to do some window shopping very soon which could inspire me.
I take RNguy and your point about the short hands. Even if it's part of the aesthetic, if you don't like that is that. I will be staying the course with the 2 or 3 hander. It's been long enough now that it seems a shame to get distracted.
Funny re: dress vs sports watches. Even though I work in a casual work place and don't dress very formally, I've found my interest in watches going the opposite direction to yours. I've been increasingly interested in more classically styled dress watches, and find myself fascinated by things like grand feu enamelling or anachronistic three-quarter plates. That said, my RO and Reverso probably get the most wrist time, and they tend to fall within the intermediate range of dress to sporty.

Thanks for the additional encouragement/enabling . As mentioned, above I will probably have some time to do some shopping/trying on/ idea gathering this weekend. If I were getting a JLC...it would be a Reverso. My father has a few nice pieces from Lange, JLC, and Patek...(a moonphase, a power reserve/grand date, a travelers watch with 2 hour hand in different colors for diff time zones, and another is a chronograph), so I don't want to get anything duplicative...as he has said these will be mine someday (luckily no brothers).
I haven't done any serious watch shopping in a while, so visiting a few boutiques/ADs should be fun and give me some ideas.

But as mentioned if you like it, they make a very high quality product that should keep you happy for many years.
I have a similar issue as my father - though not a collector - has a few nice watches that will eventually come to me. For example, he has a white gold IWC Portuguese Chrono, which has led me away from more dressy chronographs. Likewise an AP Jules Audemars with date and central seconds....This is why part of my initial search for a 2 or 3 hander focused on ultra thins, or 3 hand watches with a sub-seconds dial.
Given the watches you will eventually inherit, I think the ultrathin Piaget option seems like a good one. Watches that sing to you, and which do not duplicate what you already have. I was tempted to say something like a Lange 1 or Datograph, but give the number of times you've have mentioned the Altiplanos, they seem a more sensible choice. The slightly lower cost also leaves room for Mrs Dino to splash out without breaking the bank.
