Can you catch the Omicron and Delta variants simultaneously?

And would you become twice as sick?

Yes, but it probably wouldn’t be much different from catching either on their own though since the same antibodies work on both (to some extent). It would likely be worse to get flu and covid simultaneously since they would bind different receptors and require different antibodies to be made, straining immune system resources. 

Speaking of flu, influenza viruses actually count on this happening occasionally as co-infection with two strains of influenza can allow exchange of RNA and rapid formation of a new strain. Influenza has a segmented genome (it is 8 separate pieces of RNA), it’s possible for the fragments to be mixed up if two different viruses infect the same cell.
