Baby Gates and Brownstone Stairs

I’m looking for a way to make a child safety gate work with a brownstone staircase. The gate would fit at the top of the stairs, where there is a large newel post. The issues are (i) i’d prefer not to drill into the newel post, for obvious reasons; (ii) i don’t want to use pressure-mounted gates, as those aren’t very safe for staircase use and they don’t really fit right anyway; (iii) the stair-friendly gates i’ve found so far don’t work with big newel posts (i.e. they come with clamps that can’t fit around anything wider than a skinny post); and (iv) our stairs are relatively narrow so some gates don’t fit at all.

i’d appreciate advice, experiences, etc. on dealing with this sort of situation. thanks in advance!
