Would variants of AES provide the same level of security as AES, say by just replacing the S-box with another one, MDS matrix of Mixcolumn, etc.?

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

What research did you do? I’m asking, because you seem to be unaware of already existing questions like… Replacing the Rijndael S-Box? – e-sushi Aug 21 '14 at 14:33

There is book Algebraic Aspects of the Advanced Encryption Standard thats gives a good algebraic description of the AES algorithm. Reading it you'll see that there was some freedom in choosing some parametres to fix a standard. Changing this choices, but keeping the algebric properties should give you an equivalent algorithm. This mainly means you can change the irreductible polynomial used to define the field, ...
