Well, if you are thinking of an XGT case, then it wouldn't be a reedition at all..
And JLC has already issued quite a number of interesting complications in the reverso over the past 15 years.
The 'old' reverso was a simple, no complication wristwatch. Anything complicated would therefore not be a reedition.
I myself wish that they will return to creating complications for the GT-sized reversos, as only XGTs and Squadras get the attention of JLC development team these days, which I think is unfortunate (I just can't bear with the proportions of these 2 watches, which are also way too large for my liking)
Thinking of the reverso, JLC already did a reedition of the early reverso (no second hand, black dial, art deco numbers) a while ago, but it was a dealer limited series only.
The one I think they reissue / adapt in GT size if they want 'something new' in the reverso line while keeping the heritage lineage is a reverso SC
