Welcome back, Red. You have been missed. And congratulations.
Not sure what variety of clover you are talking about or how it might grow in your climate. The clover I'm most familiar with is red clover grown for hay. That gets much taller than 4" so not close to the same thing. The kinds of questions I'd ask are how often do you need to mow it and how will it look after it is mowed? Will it still be green or will it look like brown stems until it regrows? Can you use a mulching mower on it or will you need to bag it? Clover is known to be a great food for several different critters, will it attract critters you don't want? Not just deer, maybe rodents? Will it crowd out weeds and grasses so you don't have to mow anyway to keep them under control?
Personally I'd be reluctant until I saw an example of where it has worked elsewhere.
clover will not crowd out grasses enough to control them. rabbits/etc will selectively eat it and leave the surrounding grasses/weeds.
i've tried to use taller forage plants to control and keep grasses from doing much but they won't work for long. the wind, birds, the existing seeds in the soil, etc all will try to get grasses regrowing. and it is extremely difficult to weed grass roots from out under things like alfalfa and the larger birdsfoot trefoil plants. it was a lovely garden for several years, but it is being taken over by grasses now too and being mowed until i can turn it all under again and plant it with veggies. the soil there is very nice now after several years of chopping it back and letting the worms turn all that nitrogen rich green stuff into plant food. it was my green manure space where i could use those greens for top dressing vegetable gardens.
