It's just not really all that feasible because it goes one of two ways:
1) It's basically BM on steroids, where you have a fully capable pet tank that can handle current raids and a player-controlled avatar doing competitive (ish) DPS, making this the "go-to" combo since you effectively get two free DPS slots without increasing party size
2) The pet is directly controlled by the player in a "merge/mount" scenario, where the player is hitting all defensives, generating threat, and basically just being a melee tank, but the pet absorbing the damage.
At the end of the day, the boss needs to punch something, so sure, patchwerk style can work (assuming it doesn't stray too far from the other tank for "reasons"), but in every fight in Nathria, for example, an AI/partial player controlled pet tank would be an absolute nightmare, especially if the DPS person dies to a mechanic since they were trying to micromanage the tank pet and that tank pet just goes *poof*.
