Is it possible for a wisdom tooth grow connected to the tooth in front of it?

Possible: Possible but unlikely. There are condition sknown as "gemination" and "fusion" however, they are more comonin primary teeth and usually in the incisor region.

Unlikely: Teeth can grow connected together like siamese twins. However, this is rare.

Anything is possible: But it is highly unlikely. I have seen this in front teeth, never in wisdom teeth. However that being said, wisdom teeth can be very quirky.

Rare : I have never personally seen this happen in over 40 years of practice. While not impossible, it would be rare. It is more common and not rare to have "extra" wisdom teeth behind the 3rd molars or normal wisdom teeth. I have seen that scenario (supernumerary teeth) many times over the years.
