I don't think you understand russian mentality. If it will be the only option, they will run their space program, however gutted and affected, from grey market. The war will only strengthen this mentality and approach.
Just don't expect thats the same grey market that we individuals are exposed to, currently places like Turkey, Georgia, Belarus and plenty of *stan countries are happily providing all the banned wares. Its not like they need to buy enriched plutonium (of which they have plenty), rather just chips and few things around.
Or they go completely China way, they can pay in raw materials like platinum, oil, gold, diamonds etc.
