Some airlines do but it causes other issues.
United often mix larger 737s and smaller regional jets on the same route during the day. The complications arise when trying to slot them into other routes when otherwise idle; either they're too much aeroplane or not enough.
If they're fully amortised then you can just park them for the rest of the day, but crewing becomes an issue.
An extreme example is Lufthansa which is operating a daily mix of A321s ( ~200 seats ) and 747s between Frankfurt and Berlin this month to handle the ramp-up to Christmas.
