What could this mean??? (Road Ahead 10-5-18)

Assuming for a moment I am correct about it being a Polybius cipher, there now exists a distinct possibility our friend CG_Crumb took it a step farther and over encrypted it.

Why? Because the name for the most popular overencryption of a Polybius cipher is a Nihilist cipher. Nihilus=Nihilist? It's a maybe to be sure but given that this is more of a stumper than most clues, this level of complexity would make sense.

Top portion 13 gold letters General Grievous.

Just commenting to check in on this tomorrow

Can you double-cipher something without it turning into mush? Like put it in one cipher, then that code into another?

I was gonna chime back in to the thread I was in earlier but Kyno shut it down. While I do enjoy the long Road Ahead reads, this puzzle is quite glorious and meets all my expectations for today, even if it dropped at 11pm(eastern). Well done, @CG_SBCrumb

In the first picture, 7's are not written like the #7 in aurebesh.
Depending on how it is written, it could mean D or R
4
55
555
4 B 41
495 A 5
95 A 4 B 4 D
495 R 4 F 54
58594 D 4 E 4
F 4 E 4 F 45555
14 F 5 A 544 D 4 F
43584 R 565248
4 E 58494555544
D 434 B 554 D 4 B 594

Oh yes. Makes it very hard to translate without the key. If you have the key, you're golden. A standard google search came up with some tools that may help folks ti understand the cipher system but not necessarily translate this message.

Okay, taking the upper block as one big lump of hex code and ignoring the gold letters, we get the following hex bits:

45 55 55 4B 41 49 5A 59 55 51 59 5A 4B 47 49 57 4F 54 58 59 47 4E 4F 4E 4F 45 55 51 4F 5A 54 47 4F 43 58 47 56 52 48 4E 58 49 45 55 54 47 43 4B 55 47 4B 59 44 47 55 4B 42 41 54 4B

That gives a cyphertext of:

EUUKAIZYUQYZKGIWOTXYGNONOEUQOZTGOCXGVRHNXIEUTGCKUGKYDGUKBATK

Will work on the latter part now, but that may be helpful for anyone else currently working on it.

Corrected hex is:

45 55 55 4B 41 49 5A 59 55 51 59 5A 4B 4D 49 5D 4F 54 58 59 4D 4E 4F 4E 4F 45 55 51 4F 5A 54 4D 4F 43 58 47 56 52 48 4E 58 49 45 55 54 4D 43 4B 55 4D 4B 59 44 4D 55 4B 42 41 54 4B
