You can mod the sockets on a BP6 to take coppermines, we did that to a friends board back in the day. No idea if it would subsequently take Tualatins in adapters though!

Using an ISA riser card on the VP6 maybe?

Will that enable me to address the ISA card from HMI drivers or DOS games in broad terms?

You can theoretically add as many ISA slots as you want. It just comes down to power requirements and signal clarity.

The ISA bus is all shared so there isn't anything special you have to do to have more slots. You can access them the same exact way as the slot on the motherboard.

Can I use this to connect a SoundBlaster AWE32 to a PCI slot and have it accessible to DOS games?

No. The white port is PCI. The black port is ISA. If you look closely, you will see that the ISA port is just a passthrough and not connected to the PCI port at all.
