Here's a sentence with a conditional:
Most probably, yes.
Yet, in terms of form, it can hardly be distinguished from an ordinary future-in-the-past. To make sure it's a subjunctive, you might want to shift it into the present - to eliminate any reason for a backshift:
The staircase IS so narrow that I wondered how I will(?)/would get past if I meet(?)/met someone coming down?
{BTW, the question mark looks redundant.}
Let's leave it in the present for clarity and regard it as a conditional with a subjunctive:
The staircase is so narrow that I wonder how I would get past if I met someone coming down.

Would it be grammatically correct to use "should" instead of "if" in the context that suggests that meeting someone on that stairway is very unlikely?
Why not..?
The staircase is so narrow that I wonder how I would get past should I (happen to) meet someone coming down.
Sounds, they say, a bit more formal, this way.
If you shift it back into the past, the subjunctive should remain intact:
The staircase WAS so narrow that I wonderED how I would get past should I (happen to) meet someone coming down.
Getting past and a chance of meeting someone are still viewed as future actions from the reference point in the past.

What ails me, kind of, is the sequence of the past "I wondered" and the present "I meet"...
Well...
First, it's not a present form of 'meet' - it is an infinitive that goes after 'should' (the form we used to call 'the Suppositional Mood' back in the horse and buggy times; beats me why they discarded that from-the-days-of-yore scheme of 'Oblique Moods' in teaching these days, btw).
Second, all those 'oblique moods' (
subjunctive, conditional, suppositional, whatever) function in a 'parallel' universe of
imagination the counterfactual, so to speak. They (the moods of unreality) are not usually affected by the backshift in the real world of the
indicative mood.
