Although I would prefer some kind of middle ground with strong story and level design (which we know that 4A excel at), while experimenting with the simulation aspects that made the STALKER games so memorable.
Does 4A have much people that worked on STALKER, and specifically the simulation aspects? Let me check.
EDIT: STALKER lead designer Andrew Prohorov is creative director on
Metro games. Lead designer Yuriy Negrobov isn't, who is part of West Games on that Areal thing.
Level design since STALKER was an open world game and Metro games are more linear. So, let's check the teams of level designers on STALKER:
Metro games (Andrey Tkachenko as art director now, Alexander Pavlenko as lead env artist, Sergey Karmalsky as lead env artist), Acony games (Evgeniy Zaitsev), NewFX Games (Suprun Bogdan), Crytek (Yuriy Petrovskiy on Crysis 2).
Lead programmer is the same person in this interview who's now part of
4A, Oles Shishkovtsov. Vostok Games (Dmitriy Iassenev, Andrew Kolomiets, Ruslan Didenko, Alexander Plichko),
2033 (Konstantin Slipchenko), Samsung (Vladimir Tunduk), Logicking (Yuriy Dobronravin), Ubisoft (Viktor Reutsky), Gaijin Entertainment (Roman Marchenko).
On game design front, some are at Vostok games (Alexey Sityanov), some worked on
2033 (Vyacheslav Aristov, Denis Volvach),
Last Light (Ivan Veretiannikov, Andrey Verpahovskiy), West games (Peter Dushynsky), Gestalt Games (Roman Shyshkin).
So yeah, it's possible that they could do a STALKER-like game more on the level design than programming side although they still have a heavyweight like Oles who would just need to want to do a more open world game.
