The signs should clearly state 'Thameslink branch' with signs to the 'Great Northern' branch within each station, and vice versa, as appropriate. Otherwise, it will confuse some people coming in on one branch and needing to use another (e.g. Cambridge to King's Cross, over to St Pancras to Brighton). After all, First do keep both Thameslink and Great Northern names in use - for producing timetables and giving real-time information etc.
I also think it's ludicrous to have two ticket offices (and no doubt a third when SET begins later this year) when there's simply no need for each TOC to have their own branded rooms and machines. Ironically, the EMT ticket office will sell a FCC ticket - but many people going on FCC will assume they need to queue up at a FCC ticket window.
I hope King's Cross with its new ticket hall (and those wonderfully restored brackets!) will end up with just one big ticket office and no split for each TOC - but my guess is that they'll be divided up in some way.
To keep on topic; King's Cross Thameslink could not have been upgraded to allow 12-car trains to stop without having to comply with the latest regulations. That would have almost certainly meant wider platforms and lifts for step-free access. It would in fact have been necessary to totally demolish the current station and start again, and then you'd have to question whether it was the best location - especially for people actually wanting to go to St Pancras for HS1 or EMT trains who would have been walking for ages.
