Understand the fact that both has real time monitoring and virus engines as
such possible scenario as conflict would occur " It's like having fort knox
in your system - worst scenario " nothing can go in and out.

And also it would slowdown your system, other than that this products have
their own firewall imagine having 2 of them - it is possible to run both but
in my experience it can cause more harm than good in your system having
both. As per rule of the thumb have one Anti-virus - one Firewall and well
2-3 anti-spyware with 2 of them anti-spyware not running their real time
scanner and should serve only as a back up for second opinion or should the
all other running cant take out an infection.

I'm not planning to have them running simultaneously. The idea is
that at any time one of them will be installed and running; the other
will be installed but disabled.

At any time there will be only one real-time scanner running, and only
one firewall running, so I don't understand how I can have the sort of
problem you describe. Or am I being naive?

The sort of problem I might expect is:
- One product refusing to install until the other product has been
uninstalled.
- One product refusing to install updates until the other product has
been uninstalled.
- One product thinking the the other product's definition data
contains a virus.
- One product doing things even though it's supposed to be disabled.

Are any of these likely to happen?

This may likely to happen

1. "- One product doing things even though it's supposed to be disabled."
This product have services running all the time updates or among other
things
2. "- One product refusing to install until the other product has been
uninstalled." ( Lately some of the AV's does this action and well quite
often dont literally uninstall on your queue they tend to leave remnant
files and a total headache )
What if along the way one of the product committed to an update and
such update
proceeds to detect other AV / Security apps.
3. " - One product thinking the the other product's definition data
contains a virus." ( I encountered this once it was a mess )

This I would add:
What if the other AV detected and quarantined a file or such an infection -
can you manually tell the
other AV not to detect or do same thing to the said file ( detection occurs
not by namesakes but
by specific algorithm of a file ). They will end up chewing each other.

But then again this are just an option the final call is yours to make.
