Being as the USSR
, with a then focused programme and with then less budgetary constraints and no overt political opposition struggled to make Buran operational, before the USSR
imploded taking a large part of their space programme with it, I cannot imagine this long dormant programme coming back.
The last best chance was around 1992, when ESA finally dropped the vainglorious Hermes mini shuttle, they might have been minded to put some cash and maybe some help (avionic systems?) Russia's way to provide in a few years a alternate craft to the US Shuttle.
Buran was a terrible mistake, after the long delayed, technically fraught Soviet Manned Lunar programme, finally wound down in 1974, those who had fought hardest to achieve this, got what they wanted, a rival to the US Shuttle, which these Kremlin hard men had convinced themselves was some kind of orbital bomber, a first strike weapon against the USSR
While Shuttle had military applications, these did not include being a weapon system itself.
Those in the Russian agency concerned with actual space exploration, who's worked on the Mir programme for example, were dismayed at Buran, seeing it as an unnecessary extravagance, they might have wanted an eventual Soyuz replacement, but something much more modest than Buran.
However, it is sad that the Energia vehicle was lost, that heavy lifter could have been very useful, considering NASA's apparent new commitment to exploration beyond Low Earth Orbit.
