theorycrafting a temple layout with generator on start of 2nd chain

Hi guys, I did a theorycrafting of a temple layout with generator on 2nd chain. Please take a look and let me know if it can be improved or if there are better layouts than this?

Let's share discoveries and insights as I am constantly on the lookout for better way to build the temple.

I have theorycrafted a second layout where the generator is on 2nd chain.

This layout has one room less but the u-turn of the 1st chain (at bottom right area) is similar to fubgun layout, hence it might more familiar (and hence easier) to attempt.

If anyone has better layouts, please share and let me know. Tks.
