thinking about 'Goro Akechi' not actually being his real name and i have some silly thoughts
Goro Akechi being a fake name he picked because of the character Kogoro Akechi is very funny i think; however, i am very attached to Akechi as his surname so for your consideration:
Goro Akechi is his actual given name, while still being a reference to Kogoro Akechi because it was his mother who chose that name for him!! she poured all her childhood dreams of being something great and her dying hope that her son, the only person she has left, will be able to overcome their circumstances and make something of himself.
or, alternatively: Akechi is his real surname, but Goro isn't his real given name, and he chose to change his name (either socially or legally) to reference Kogoro Akechi because he's a nerd but also because of his desire to seek justice, so he named himself after a famous fictional detective that he looked up to in his chilldhood
