I have another suggestion. Could the suffragette line from barking riverside to Gospel Oak be remastered so it features the new tsw core features including passenger and station announcements, also more detail like adding banners and route maps to the train interiors? That would be great to see!
You're not gonna see anything released in TSW3 or later getting remastered quite just yet, also what you've suggested wouldn't fit the title of being a remaster anyway. JT's Blackpool Branches and WCML over Shap got station announcments when WCML CRE-PRE was released as normal updates. And adding banners to the 710's interior is such a small addition that it likely wouldn't be added on it's own, but is possible. An update to that route I'd like to see is the LU Class 484 from the GWE remaster having an Ai only layer at Barking for the Hammersmith & City and District line services since Barking is way too quiet.
