It is just that in my organization, we have certain custom protocols whose
UDP port numbers are much more easily recognizeable in hex rather than in
decimal because the designer decided to be cute when choosing the port
numbers.  But, I certainly understand that this may not be something that
applies or would be useful to the general community, as Micheal says,
because you can always read the hex from the original packet bytes.

No, I don't like that idea.

TCP/UDP ports are commonly represented as a decimal value in programs 
and documentation. Adding a hex value will make things confusing IMHO. 
As Micheal noted, you can get the hex value from the "Packet Bytes" if 
you need it.
