I guess it can be tricky, but not impossible. I'd be really surprised and blown away if it turned out to be impossible.
I sent to the list about a year and a half ago, when I was writing some externals, asking about this, and I remember Miller gave a suggestion, saying it's not the most elegant but it might work. Can't remember what it was, as I never used it, but if you search the list archives, you might find it. Max has a routine that checks whether there's is a signal connected to an inlet, and this way you can choose between the argument or the incoming signal. But Pd doesn't have that afaik..
And I guess it is actually impossible to work this out in a patch, huh? I wouldn't be surprised...
I'm pretty sure that yes, it's impossible. But it would be nice if someone can prove us wrong here..
thanks
