If resource packs ignore storage limits, is it possible to rebuild the Clan Castle at TH2 instead of at TH3? I don't think there's a TH limit on it, so maybe.
"The Clan Castle ruin is repairable at Town Hall level 3 through regular gameplay. It is not available at earlier Town Hall levels, even with Gems, as it is impossible to construct and upgrade Gold Storages to accommodate the needed amount until Town Hall level 3. ('Clan Castle.' Clash of Clans Wiki. N.p., n.d. Web. 07 Jan. 2017.)"
Although, it was impossible; it might be possible now. Before I assume anything else, the real question would be: does TH2 even offer any packs? If there aren't any (if you've went ahead and tried to prove it), maybe it just takes a couple of days for new players to start seeing them. On the other hand, SC could've seen this exploit and enforced a TH requirement on the resource packs themselves.
