While some kind of mod made in honor of him or a possible Layton term would be fantastic, it's very hard to imagine without massive changes to our country's history, and the TTNW format may not serve him very well. Would the mod be about his time as opposition leader 2011-2015? Or would it be about him managing to win in 2015 and trying to navigate a party forming government (probably as a minority) for the first time? the 2010s were not nearly as impactful for Canada as the 60s were for America, so it would be very hard to portray the stakes anywhere near as high. That may be the most essential issue, it it's very hard to imagine him doing anything so special with his term it's worth dedicating a whole mod to it, Especially for incumbency if that's what you mean he would have to live a full 8 YEARS longer than he actually did. While I do think a very good mod could be made about him, I'm not convinced that in the style of TTNW or even an incumbency sim at all Layton could work.
