sounds smart to me, and solid core, well made, can be purchased in a narrow width (cost less) drilled or notched for wires, cut to depth or length, ....
I once used a hollow core door for a kitchen counter, back in college days, no money, so proud to get it done for the wifey.
That dark brown cork that was popular in the late 60's on the wall above it.
It was Brooklyn, turned out the Roaches loved hollow core doors.
