hmm, no, I would change a few things.
Keep it simple and streight.
1. In Nuendo (I use old Cubase 5), route all audio tracks (mixer-channels) that don't need any Scope effect to Nuendo's ASIO master out bus, and via ASIO lead it to a dedicated clean channel of the Scope mixer, streight to mix-out.
(Of course, use insert or/and send effects in Nuendo where needed).
This is your clean 'collect' route, it's always there to f.e. dump any bounced track to
2. Route all Nuendo send effects to the same (clean) master channel.
(Unless you want to manipulate this or that Nuendo effect in Scope, in that case use a second Nuendo ASIO bus out.
Normaly you don't need effects on effects.
Summing chanels to one isn't a problem at all, it are the musical choices you make that do matter ).
3. Give any Nuendo track that needs special treatment in Scope a separate ASIO bus -out and therefor a separate Scope mixer channel, to add insert or send effects of your choice.
Try to 'group' the tracks to the appropriate busses where possible, to keep things clear a bit.
4. Don't mess with 'linked' fader volumes in Scope and Nuendo, much too complicated.
Think linear, you start in Nuendo, bus everything to Scope, and monitor from there on.
Keeping Nuendo 'flat' (keeping volumes and everything at o dB or default) is for the purists, don't worry about that, make music instead

Don't want to be too smart, the one that finishes a nice song first is the smartest
5. Wanne record a midi track, or bounce an audio track together with it's effects?
Simplest way yet very safe do this: first make sure you always monitor the mixer's master out ( you'll hear exactly what you record...)
Route this same mixer-out also to your ASIO destination (any output can have more than two output wires), to be able to stream it into Nuendo.
In Nuendo, solo the track that you want to record (or bounce), and record...

Enjoy while listening to this proces
(Don't insist on 'export audio', it's quality seems to be less, and it works only on the master bus, profis don't use it).
Also, combine tracks if you want, to bounce them to a stereo track (like drums).
6. Wanne record the whole mix?
Solo all tracks and...ehh no, just play everything and record the Scope mixer's stereo-out on a fresh Nuendo track
7. Wanne record more channels at once on separate tracks?
Solo those tracks, and learn to use the Scope mixer's bus routing, and route the busses to different ASIO channels to record those on different tracks in Nuendo, therefor check Nuendo's multitrack recording settings.
I myself never use this function
8. And globally: use automation in Nuendo where needed, and record midi cc controlls for Nuendo VST(i)'s and for Scope synths/effects/mixer etc.
Just use whatever you need to controll the mix
This is in a few words the way I do it, you can check the results on

Keep it simple and linear, and all will be fine

Hope I didn't tell you the obvious
