Implementing different layer 2 solutions for Ethereum

im writing my Bachelor Thesis in Computer Science about Blockchain and Ethereium in general. My aim is to benchmark/analyze the Transactions per second by creating private Ethereum.

In order to benchmark/analyze im was thinking that i should create three Eth networks and each having one specific solution for scalability..

Different solution implementation:

1. One eth network has sidechain as consensus layer solution
2. One eth network has Rollups as consensus layer solution
3. One eth network has sharding as consensus layer solution
4. or whichever layer 2 solution

How realistic are these implementations, how would i even start?

Keep in mind im writing a Bachelor Thesis, meaning its not going to be at a very high level.
