Utilize all devices in local network for multi-agent setup?

What do I have:

\- Main PC running Qwen 3.6 27B at \~30t/s (do not recommend me Qwen 3.8 27B — I know it exists, but I need time to get used to this new model)

\- Wife's PC running Qwen 3.6 35B at \~55t/s

\- Steam Deck LCD and OLED, both running Qwen 3.5 2B at \~30t/s

My questions:

How would you configure this for multi-agent use? Is there any good practical use for the Steam Decks, or is it better to drop that idea entirely?

Have I picked a good set of models, or should I consider another combination?

I'm looking into a scheme with one orchestrator (I assume the 27B model is the best option for this) and a bunch of workers for smaller atomic tasks.

Is there any practical reason for this kind of setup, or am I just spending time on a dead end?

UPD: I need for agentic coding scenarios
