So far I have been managing my Bitcoin holdings using a HW in a location and in the same location I have had the seeds well hidden and written down on a piece of paper.
As I accumulate, I have been thinking of buying another HW and storing it in a vacation home, just like the seeds, in the same way, written down and hidden. It would be about handling half of my holdings at each site.
What do you think? I don't think it would make sense, for example to have copies of the seeds of both HW's at both sites because in a $5 wrench attack I could lose everything.
One drawback I see is that if the house burns down I would lose everything I manage with one HW, but well, that risk I also had now, having 100% of the management of my holdings in one site.
It seems from what I see in your plans that you want to apply "Don't put your eggs in one basket" You are doing the right thing and I don't see anything wrong.
Splitting your assets in different wallets is good because as you mentioned, even if one house burns down, there are other houses where your assets can be hidden. For me, your plan is fine.
