Since ~20% of United's 175s are parked somewhere for lack of crews I suggest that they aren't in a position to do that. Your analysis would be different if someone had RJ crews to throw at these markets but since nobody does and won't for half a decade or so (barring a major recession) I see frequency being cut to upgage airframes.
