Spotlighting speaker through 2 different zoom without making the speaker to join those 2 meetings

Hello there, i have a question about spotlighting speaker through 2 different zoom. It's kinda confusing for me to say, since i'm not really fluent in english. 

I'll have to host a competition in a zoom meetings, which i use 2 different zoom meeting (1000 participants meeting and 500 participants meeting). Is there any way for the meeting consists 1000 participants can have the same screen shown of the speaker with the 500 participants without making the speaker to join those 2 different zoom meeting, which the speaker only joins the 1000 participants meeting?

I hope my question can be understandable, Thank You.
