Is there any advantage in replacing the existing coils with double/double coils?
Is it OK that three of the transmissions: Schumann, T1 and T2 would be at a much lower power?

From Thomas

Advantage – from an advantage point of view it doesn’t make a lot of difference. It’s the numbers that are important. Less Power – that again is OK for the same reason.

As I said, it’s fine to do the job and make things simpler – but don’t overtax yourself. There are things coming up with the Ascension which could take up your time. You really could try doing some Meditation during the day for instance.
