This is a pretty fair summary. 1809 would become close to 1813 as Wagram (which was already a close run thing) would be transformed with an extra 100,000 Russians.
Not only the Finnish war is butterflied in all probability but Russia probably settles with the Ottomans and Persia in the South in 1807 instead of broadening the war.
I don't think the Russians at this point have the ability to support and supply 100 000 men that far outside Russia - they had 60 000 at Austerlitz, 67 000 at Preußisch-Eylau and 145 000 at Leipzig - the Russian Imperial Army reformed and advanced a lot during these years, especially when it came to logistics, staff planning, marching dispersed and concentrating, allowing them to field, support and supply much larger armies further from their own territory.
70-80 000 would be stretching it, and they would need to gain control of or at least containing Congress Poland/the Duchy of Warsaw before moving deep into Austria. Napoleon have not lost his veterans at this point, and migth very well be able to keep the Austrians and Russians separated through manouvre warfare and defeat them in turn.
It took until 1812 for the coalition(s) to learn to be resilient and stay in the field even with hard defeats to keep the pressure up on the French.
Then again, with continued war, the Russians may learn Napoleonic warfare faster.
