It is possible.
Check my program https://github.com/PawelGorny/lostword
Currently there is option to check all possible seeds with a given words if one word is missing and then check balance online. But to be honest it is not very useful...

As I understand you have list of words: word1, word2, word3...  word12 and you want to check which combinations are correct (have correct checksum), right?
I could do this... technically.... but output will be huge. For 12 words it is doable. For 24? It will take years...
