GE Aviation no longer lists the -1B54/P2 among its offered engines for the 787 - and I think it also had the 111.1" diameter fan.....

Unless they would do an updated, de-scaled, bleed version for this mooted 767X.
The -1B54/58P2 was never an offered engine for the 787 family. The 787s use the 1B70 (788), 1B74/75 (789) and 1B76/78 (78X)
However I see the 1B58/P2 has higher potential for the 767X due to its thrust is quite close to the 763ER's thrust. A PIP would be perfect. GE may be developing something called GEnx-1B58X/P2, of course base on the mentioned 1B58/P2, but a lighten and (slightly) uprated version.
