Housing dynastes 4 dynastes grantii larvae + other stuff

[beestle]

I had recently bought 4 dynastes grantii larvae from bugaincybrrspace and was wondering if I should house them together. This is because I want all of them emerging at around the same time. Just wanted to make sure that I could do this with info from pros. 

 

Also, is white rot wood okay for d grantii to eat? Ive seen some on and off stuff about them eating it so i just wasnt sure. As always, thanks😃
