Hotstring doesn't trigger when it contains remapped key

[Arrivest]

Suppose I remapped my / this way:
; semicolon + k = /
`; & k::/

; restore semicolon
`;::;


Now, if I want to have the following hotstring:
; never forget adding a space after //
:*://:://{space}
It won't fire if I use my remapped /, but will fire if I use the native /. Is there a way to make both work?
Thanks!
