As the bytes you suggested to zero-out have different values in different savegames, I suspect they may hold additional information. So I tried to find a minimally invasive way.
First, (for me) it suffices to change the second byte you mentioned. For the record, in the sequence
4c 55 43 5f 42 72 61 6e 64 6f 6e 5f 50 6c 61 6e 00 0c 00 00 00 04 00 00 00 XX 1d 00 00 0a
corresponding to "LUC_Brandon_Plan...".
Second, it is not necessary to set it to zero. At least here, it sufficed to set the 4th bit (counted from the lowest valued bit, i.e. from the right) to zero.
I hope this is less likely to trigger unintended side-effects.
