Creating a Pi HAT

Hi there! I’m trying to create a Pi HAT for a Pi 4 that will mount onto the 40 pin GPIO. I want the hat to have an HDMI out, USB out (hopefully 2 usb out if possible), MicroSD slot and, if possible, a USB-C for power.
Is this possible? If so, where would I find the HDMI connector in Fritzing?

It is possible, but possibly not that useful (except to make boards.) The typical PIs don’t implement the HDMI connector and there likely isn’t a Fritzing part. If you have the data sheet for the connector you want to use it is probably easy enough (for me anyway) to make one.
