Commercial Switches (for example the HP 25**, 28** devices) had a
limit on number of VLANs (I think it was 32 out of the box, I
increased that first thing after unpacking), but never a limit on the
range of VLAN IDs. You could have VLANs 1, 250, 100, 3847, but not
more than 32 of them in the default settings.

I don't remember, it was too long ago. I think that I didn't even get
past the "get a working compiler" stage after unpacking the OpenWRT
build chroot. I think I even set up a CentOS VM to make sure that my
Debian host didn't interfere with the OpenWRT build process.

It's cheap if you Ebay it in the US. In Europe, it most likely was
never on the market, Ebay Germany does only have a single offer with a
price of well over 80 Euros.

That's what I intended to do, yes.
