The main reasons I’ve seen from vegans for not eating meat seem to be all about the morality of eating a sentient animal, the practices of the modern meat industry, and the environmental impact of it. And don’t have anything to do with the taste of meat.
Since lab-grown meat doesn’t cause animal suffering, and assuming mass production is environmentally friendly, would you consider going back to eating meat if it were the lab-grown kind?
I think the actual question is do you feel you can eat lab grown meat? Ethically it meets all the requirements of vegan, as there is no animal suffering, no consent, and muscle tissue cells are less sentient than a plant.
