IIRC, even largest variable cycle engines considered for ESAV or LRSA (200 klbs+ TOGW) were smaller than F135.

Part of the appeal of say a tailless aircraft is a reduction in the thrust requirement from the engine(s).

This would require a bigger engine than the F-35:

Also, the language used in the article isn't clear as to whether the variant for the F-35 would have a 3rd stream. Regardless, this (and other) articles are pretty clear - the follow on variants will be larger and more powerful than those for the F-35.
