I have installed 3/4" flooring downstairs in my home, replacing the 3/8" that was there.  An unintended consequence of this has been the front door sweep is now catching on rugs, so I haven't been able to have a rug down at the front door.  After 1 winter of this, I have decided this has to be fixed.  I was thinking I could remove the old threshold, put down a weather treated shim of some sort that is >3/8" in height, put down a new threshold, and then cut my door to fit with the track saw and appropriate blade.  However, I wanted to see if anyone had a suggestion or sees a potential mistake in my logic here, as I don't want to discover a problem halfway through and find myself with no front door.  Thanks!
 
I saw this exact fix on Ask This Old House, Tom Silva made the fix with new parts on the threshold, and I think cutting the door as well. Let me see if I can find you a link....
 
Cutting your front door down could be a real problem. You'd need to put a new finish on the bottom of the door that will be 100% watertight as your door is likely to get wet and have water run down it. It could then wick the water up and cause you a lot of problems.

Your options as I see it

1- cut down the door : I wouldn't

2- raise the door: a lot of work

3- a concealed door sweep like this https://www.tmhardware.com/Door-Sweep-Mortised-Aluminum-with-.406-Nylon-Brush.html ( great option as you could route the groove and set it to whatever depth works for you.

4-  recess a door mat like this https://www.pinterest.com/pin/197173289909467303/ ( i like this option)

Hope one of these works for you!
 
I have watched the Tom Silva piece in the past, and just watched it again.  The main differences are my threshold is on top of masonry, not wood and a toe kick, although i don't think this would be a problem ,and he doesn't raise the level of the threshold, but i don't believe that would be an with a piece of PT lumber planed to a proper thickness.  In regards to sealing the bottom of the door, I hadn't given that much thought.  I (probably wrongfully) assumed placing a new piece of weather stripping would be all it needed.
 
There are many applied bottom weatherstrips available for almost any situation.  National Guard products and Pemko both have weathersealing solutions for any circumstance.  I do commercial door installs of wood, steel and aluminum entrances and these are the manufacturer's products that we use.  Both have web sites that show what is available and with a product # you can do a web search and find a distributor.
