The grenadiers seem to have had the same uniform as your average enlisted Swedish soldier. The baltic and german companies in the game could have the grenadiers that are currently in use for the Swedes. The Livgarde did have a bit of a different uniform than the average Swedish soldier. http://www.tacitus.nu/gnw/armies/sweden/livgardet2.htm
See the link for an example. Narke-Varmland and Jonkopings Regiments had red piping like this modern drawing of the Jonkopings Regiment battle of Helsingborg shows: https://www.artstation.com/artwork/lWlXY
The karpus itself is very tricky and was generally replaced later in the war by the tricorne, and if the artist is not on contract these earlier units, that's fine with me. I'd keep the Dalregementet the same though as it currently is. Oh, and Narke-Varmland had the most men at one point in the Swedish army I believe. I think that might have been at Poltava, so if another company or two was added to that regiment, that may not hurt either. http://www.tacitus.nu/gnw/battles/Fraustadt/swedes.htm
Here's a link with the uniforms at Fraustadt. It'll show ya what Narke Varmland wore. Oh, and one interesting thing to note is that the Swedish uniforms at some points in the war were so worn down that they were hardly recognizable. I read in a book by Oscar Browning that at Poltava, the Swedes put straw in their tricornes to show they were on the same side. The winter of 1709 took a toll not only on the troops, but on the uniforms as well.
