You’d need four rails, a 9 cm separation isn’t enough to fit two side by side. This solution has been ruled out as technically infeasible (I don’t even want to think about what the switches would look like…)
Adjustable-gauge rolling stock has also been ruled out as incompatible with the Finnish climate.
The most (only?) feasible way to do it is to “simply” build entirely new standard-gauge track next to existing track (and then possibly start upgrading the latter too at some point in the future).
Adjustable-gauge are used in Switzerland for a mountain line (Montreux-Interlaken) all through the year. I have never seen temperature issue mentioned.

Given the small difference, maybe the easiest option is to "just" update the wheel axles of the entire fleet in the same time and at the same speed as the tracks.
Wheels are anyway wearing parts and are to be changed periodically.
Part of the motivation is removing the Russian gauge rails such that they can't be used in the case of invasion, so I don't think dual-gauge is really an option here.

When engineers asked should we do the rails same width like in europe or wider, the answer they got from tzar was "Нахуй шире"
literal translation "wider by length of dick, but meaning "why the fuck we need wider"
- В Европе ширина колеи 1435 миллиметров. Нам делать так же или шире? - Нахуй шире, - ответил император.

BTW, I'm just speculating out loud.
