It's possible, but it's highly unlikely that anyone would bother
creating what is essentially Gravatar for GPG.
Especially since the protocol already supports key owners including a
pictrure with their key. Most people don't do that either.

You shouldn't need to memorise it. In Enigmail you can create rules
for addresses to link to preferred keys, as well as set whether or not
to encrypt all messages or just sign and so on. Most MUAs which
support GPG provide some method of doing this and GPG itself supports
that function with group lists in the gpg.conf file.
If the version of GPG you have installed supports it, you should
probably add this to your gpg.conf:
That will gradually build a more practical web-of-trust which keeps
track of seen keys for you.

Yes, this has been possible for a long time now. Most people use a
64-bit view for that reason. This is now the default view in GPG 2.1,
along with displaying the full finterprint. If you do not have GPG
2.1.x installed, such as if you're using GPGTools on OS X or GPG4Win,
then add "keyid-format 0xLONG" to your gpg.conf file.
