Yes, with a performance hit, it is possible, at least with Virtualbox to install a 64-bit OS on a 32-bit host. Mileage varies based on the host and guest. I’ve pulled it off a few times. I don’t know however if you can run apps that require 64-bit in such a guest without issue.
As for the other way around, I’ve never had an issue, but then I also didn’t have the situation of the host not supporting 32-bit apps either. It’s worth a shot I suppose to see if older but still functional hardware can be extended on life support a bit longer.
