That should be your bilge intake for fresh air. A safety minded person would say "bad idea"
Question is, how often do you run your blower now? (should is another question).
Devils advocate - Many older boats have cracks in the hose anyway and fresh air will still be drawn into bilge even if disconnected (assuming you don't smell fumes while sitting).
I am not sure without a fan forcing air out there would be enough convection? like a chimney with flue open but not vents under fireplace. You could test it; allow to get warm then remove hose and come back in an hour. I know with my cuddy, opening the hatch makes a difference but that is 15x15 not 3". much depends if there is a breeze blowing.
Maybe remove a front seat cushion if there is enough gap in the bulkhead?
Or take out the glove box liner? Everything that fits in there likely would fit a small container which is easier to dig though anyway
