I'm getting ready to renovate my enclosed porch. It was originally open air and had a simple wood panel enclosure kit installed. I'm planning on demoing the walls and rebuilding 2×4 stud framing… Started looking for a new prehung entry door and realized I have a problem…
The porch floor is pitched as it was originally designed to shed rain water away from the house. The door opens in over the rising floor. The current door has a pretty tall sill plate and the bottom is still trimmed on an angle and a sweep installed.
Short of releveling the floor is there any way to install a prehung door to open over the rising floor?
I can use an outswinging door as there are steps leading up to the door with no landing on the outside.
I would assume adding a footer under the prehung sill plate may work but I'm concerned that it will create a tripping hazard stepping up to walk out the door and down the steps…
To be clear this is not an uneven sill question. The door opens over a rising floor.

I can see four options, two of which have been mentioned so far:
I can see this going poorly, as a trip hazard at the top of some stairs
This is probably the simplest option, but can look odd from an exterior perspective
It could look a bit odd when the door is closed, but it looks like there are options for up to 1 5/8" (42mm) of height difference between the door being open and shut. See this supplier for an overview. Probably the most expensive.
These lift the door as it swings in, and can provide maybe 1/2" of lift. They are also self-closing by design.
