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?
Still need to investigate the sustainability of it before I would try, but presently there's no produce on sale here. But I'm pretty used to dishes without meat by now, so there's no direct need.
I suppose it would be more targeted towards current meateaters, hopefully they stop destroying life on the planet at some point.
