I think I mentioned this before in another topic, but one of the rather ironic things about the Great Northern War was that a lot of Russia's initial effective artillery was actually Swedish. Charles XII's predecessor gave the Russians something like 150 6lb cannons for their last war against the Poles (where they captured Kiev.) That's history for you
Also, having talked with Flikitos on Steam a bit, we discussed Russia's late era uniforms. Specifically, there are two options:
The 'Potemkin' uniform:
Used from 1788 to 1796
Or the more classic 'German' uniform:
This particular example being employed from 1763 to 1786.
Since the Potemkin style uniform has already been made (many thanks to Flaviuss ) it would seem silly not to use it, but then we'd miss out on the classic styling of those sexy bicorns.
My thinking is that Russia's regular army units would use the new 'Potemkin' uniform, basically reflecting the units that were stationed nearer the capital or in more convenient places getting their new uniforms first, while the elite 'Suvorov' units would use the old bicorns and suchlike, reflecting the fact that Suvorov spent most of his career fighting the Turks and wouldn't have received the uniforms quite so quickly. This also gives people an easy method to distinguish between units on the battlefield, of course. It would also reflect the reversion to German style uniforms when Catherine II died, which was when Suvorov's most famous campaign took place (march over the Alps and all that jazz.)
