Printing with different sized nozzles with a toolchanger

[Hawx11]

Is there a solution for printing with different sized nozzles during one print job?

I'm looking to upgrade my Sovol SV08 with a second nozzle and I started to ponder if it is possible to use different sized nozzles for different processes during one print job (i.e 0.2mm or 0.4mm for walls and 0.6 or 0.8 for supports and/or infill)?
I'm using Orca slicer but because I have not owned a toolchanger before I am not well versed with different options regarding multi-tool printing. I thought that if there would be information about this anywhere then it would probably be here.

If someone has discussed this already please let me know and I can remove this post if needed.

Very interesting question... I've hoped myself this can be done easily but put the topic back after some quick experiments with slicers showed it doesn't seem trivial.
I'm sure when INDX comes, this will be asked more frequently.

Quick update: in Prusa Slicer it seemed relatively straightforward (didn't test-print yet) as long as layer height is uniform. I guess the use case comes from the XL toolchanger product line.
It seems a compromise - printing with the large nozzle at smaller-than-necessary layer height reduces mechanical strength and increases print time. And printing with the smaller nozzle at a large-nozzle-compatible layer height reduces resolution in Z.

It would be interesting to hear from someone who actually uses this approach.

I could imagine some postprocessing hacks e.g. slicing twice for both nozzles, possibly even with VLH, then picking perimeter layers from one and infill from the other along the Z axis via ";TYPE:xyz" annotations, enforcing common perimeter width e.g. 2*0.45 mm == 3*0.3 mm for 0.4mm / 0.25 mm nozzles or 4*0.225mm for 0.2 mm.
But that's just creative thinking, unspoiled by reality
