If I remember my basic electronic theory correctly, the very best efficiency imaginable (but not achievable) with any transformer is 50%. That's with perfect impedance matching and zero losses. Not exactly "very efficient". Someone correct me if I'm wrong, IANAE, only a humble former radio hobbyist.
Let's not forget that innovation and improvement come not from acceptance of what is, but from envisioning what might be. The OP has a dream. Let's not stomp on it, especially if it's just to puff ourselves up trying to show how much we know.

Except virus scanners can't do anything about TPM (TCM?). Apologies if I've missed someone saying this already.
