Removing individual maps from a map pack add-on?

[SnakeEyesRaw]

If for my own purposes I wanted to remove a couple maps from, say, the Conversion Pack 2.0's BF1 folder (Alderaan and Methlyn, specifically) to save mission space so I could add two other unrelated maps into addon without going above 500 missions, would it be possible to do so? If so, how?

Thank you.

I don't think you can.

Hex edit the addme file and highlight the mission names you want to remove (example: tat2g_con) and write over them with nothing (00 bytes)

Done, it appears to have worked, although there is now a map in my map selector called "00000000" and I can't find a way to remove it from the list through the addme.
