In theory yes, so long as you can arrange for your host (or other cards) not
to start fighting over the interface. All PCI interfaces are more or less
equal.

I've never been convinced that the hard dichotomy between "host" and "plug-in"
mode is necessary or desirable. But this point of view seemed rather
unpopular last time I aired the idea.

You will need to find a way for the EBSA-285 to see the right interrupt
numbers. This is going to be hardware dependent and in some cases it may not
even be possible -- if the IDE interface is built in to your motherboard
chipset it may not be capable of generating interrupts on the PCI bus. With a
plugin card you will stand more of a chance.
