You wouldn't be looking for XT1254. You would look for
- Quark (phone development code name, like "Shamu" is for Moto Nexus 6) or
- Moto Maxx (the REAL global name of this phone).
In fact, the U.S. Moto Maxx XT1250 is
exactly the same device as the Droid Turbo XT1254, down to the FCC ID and exact same radio bands.
But Verizon demanded an "exclusive", so Motorola RE-NAMED the Moto Maxx XT1250 to be the "Droid Turbo XT1254". Nothing else changed. As the "international" Moto Maxx XT1225 has ALL the AT&T (and even an HSPA T-mobile band other carriers don't use), this phone was clearly intended to be sold as the "Moto Maxx" across all platforms by at least 3 major U.S. carriers -- Verizon. AT&T and T-Mobile.
Verizon's narcissism screwed up those plans for this phone. Due to Verizon's demands, the "Droid Turbo" was announced and released first, then a month later Motorola released the Moto Maxx XT1250/XT1225 to the rest of the world. But it was supposed to be
ALL Moto Maxx! Motorola dropped the plans for AT&T/T-mobile to release this phone in the U.S., even though at least a dozen U.S. regional CMDA/LTE carriers still did carry the U.S. Moto Maxx XT1250. But as those carriers fly under the radar, Verizon was still able to LIE and claim they had an "exclusive". There was no exclusive, not even in the U.S. Motorola released the AT&T-friendly model Moto Maxx XT1225 in Latin American countries and initially left off some of the LTE bands on the official specs, even though we knew they were there. (Some spec websites still don't show LTE band 5 for the XT1225, even though the FCC found it and Motorola later admitted it's there, when they released the XT1225 in India, March 2015.)
Then, months later when the Moto Maxx XT1225 was going to be released in India, Motorola realized there was a Max/Maxx carrier in that country and did not want confusion about any association with that carrier. So, for India, they re-named the XT1225 as the
Moto Turbo. But still, "Moto Maxx" is the REAL name for Quark, just like LG G3 and LG G4 is called LG G3 and LG G4 (all with different radios, FCC ID -- but still considered the "same" phone model), no matter where it's sold or used in any part of the world.
If you look at this official Lineage OS list, you will see Quark/Moto Maxx.

Our official CM dev
@Skrilax_CZ (who did the initial kernel work for CM12, CM12.1, CM13 and gave us OFFICIAL versions of all those ROMS -- which then allowed all the other custom ROMs for our Quark) has taken a break for a little while. We hope he's OK, but the work still continues! We've long had Nougat CM14-based ROMs and even an unofficial CM14-based ROM from
@calsurferpunk --
with recent name change to reflect Lineage OS.
And we've long had other custom ROMs
based on CM14, now called Lineage (nicknamed LOS).
I don't normally post about other ROMs in someone's ROM thread, and this AOKP Nougat ROM by
@NepoRood is reportedly one of the best. But you seem to think there's no CM14/LOS ROMS for Quark (XT1254/XT1250/XT1225) out there? Maybe you don't know about the OTHER QUARK XDA forum?
Currently we have FOUR Nougat ROMs and all are based on CM14/Lineage sources to varying degrees, especially Resurrection Remix, crDroid, and the unofficial CM14/LOS ROM.

At least two of those four ROMs have substratum theme support. I know one does not, n
