specifically themed packs are in general extremely difficult to get off the ground because out of the small few who are interested, even fewer people can find the motivation and drive to do more than a couple songs before they either burn out or find the song choice limiting

for example, me and patashu independently tried to do cave story packs. neither of us got very far

so far I don't think there has been a hugely successful themed pack ever released. I could be wrong

so basically, unless you don't care about chart quality it's probably not going to happen
