Since Buran (Snowstorm) was destroyed in 2002 along with Energia it would be like designing a whole new technology to replace it, No? In the end you'd prolly end up with 'a new shuttle' by the time it was all said and done. As much as the Russians tried to come up with something different, They pretty much came up with what NASA already Had.
The Energia launcher I think could have some potential. A modular system - different configurations of boosters and even extra stages stacked on the rocket, Could turn it into a general-purpose heavy launch vehicle.
BTW. That hanger roof collapse at Tyuratam killed eight people.
