That would be the logical way to look at it. Sony would probably see that as "Hey, Venom since is doing so well, we should pull Tom Holland from the MCU into our "spider-verse"! I pray they're not that stupid.
I would love to see Venom, Norman Osbourne, and Kraven show up in the MCU, but if Tom Hardy shows up anywhere in there, that would confuse the heck out of everyone and default Venom as an MCU movie (Which it's not worthy of being, IMO). Venom would have to be recasted.
