Orthodox Christian here. NO. The nimbus is ancient and depicts the divine light. This is hidden from us in our day-to-day but is spiritual reality. It was shown to the disciples at Mount Tabor, for example. But Jesus Christ is the Light and the Life. It is truth that is being depicted in holy icons, not random pagan traditions. That nimbus points to Jesus Christ and nowhere else.
(Orthodox Christianity included Rome for 1000 years before they started changing their faith and left the other Churches, which all stayed together and united in confessing the same Faith, and icons depicting saints with nimbuses is ancient practice right back to the beginning of Christianity, so that is why I am answering from an Orthodox perspective when you said Catholic.)
The crescent moon symbol is a hold over from early idol and moon worship cults. Mohamed unified the idol worship by moving the idols to Mecca and placing them in the Kaaba.
