That is one speculation. But it does not seem to be a good choice for intakes for the following reasons.
In 052x, the intakes are between the bridge and the exhausts. The plumes from the missiles launch from the aft VLS are blocked by the high rising exhausts. The intakes are canted forwardly, together with the round bridge, the air flow is good.
In 055, these "intakes" are flat facing upwards, less air pressure. They are blocked by the square shaped exhausts, turbulent air flow. They are exposed right under the plumes of the launched missiles from the aft VLS, choking the engines.
