not sure which worflow you mean atmā¦ sorry lol, its late XD
but i guess we just created an awesome thing in high poly and now need a low poly version for realtime/game use?
if so then you need to transfer the detail of your high polygon count model to the lower resolution version of it somehow, project all for example in the subtool palette works quite well for that,
however you might not need that if your new low poly uses the very same uv mapā¦ which could be the case if your high poly has one because it was made out of your low polyā¦ then you could just bake the textures and apply themā¦ your model however woulndt end up with as many detail as with a new low poly based on the high poly,
whatever you do lol, keep in mind that project all can take ages and not always does it work wellā¦ usually it does thoā¦
there are sooo many waysā¦ it really just depends on your workflowā¦
for most of these swords i had a uv mapped low poly version made in max already, like the last sword, i made a simple dragon head in ZB, retopoed in 3DCoat, adjusted in max, uvmapped it, exported back to ZB, detailed it allā¦
thats not always a good workflow, especially not if you create your design on the fly on ZB not knowing where it will goā¦ if you know how your endproduct shall look however, creating the low poly first as described above might be better
You should consider making a tutorial if you havenāt already, might inspire some other Skyrim players to try their hand at modelling 
Iām pretty interested in workflow too (so thanks for the pictures so far!) since Iām trying to learn methods for efficient flow between zbrush, modo and other tools -> game ready model.
