I've done a fair bit of investigation into this, making use of information provided by dedicated Hiwatt buffs. While the Tonker was *never* actually intended to be a Fane clone, it does have some Fane-like quality, but still isn't much liked by the Hiwatt fanatics. One of them puts it as "It's not in the same ball park, but it's across the street from the ball park". However, they're now stating the Tonker Lite which has a slightly different tone, is the closest you will get on the open market to the sound of a Fane "Purple" used in vintage Hiwatt cabs. Eminence's Lynch Super V12, which was designed as a Fane Purple clone, appears to be no longer in production.

As I understood it, the Tonker itself was the only speaker in the Red Coat line that was sort of a Fane clone. Are you saying the Tonker Lite, while it's different, is in some way a better Fane clone? Or is it a better clone of a different Fane speaker?
The Lynch Super V12 was actually the closest Fane clone in Eminence's Red Coat line, and are almost identical to the Reeves Purple. Unfortunately, Eminence appear to have stopped making them. Some people also found them a little too dark. So now it's either the Tonker Lite or BBQ FC12s. The latter are a clone of the Fane Crescendos, as used by Dave Gilmore. According to the very experienced Hiwatt gurus, the Tonker Lite is much more like a Fane Purple than the regular Tonker.

Years ago, I put a Tonker and Swamp Thang in a Fender Cyber-Twin. The amp had its own pros and cons, but in my mind, that speaker pair really brought the thing alive compared to the Celestion G12T-100 pair that came stock. A year or two later, in hopes of reducing weight, I replaced the Tonker with a Tonker Lite and I replaced the Swamp Thang with a Lil' Texas (I think...). I wasn't nearly as happy with the change. I also did a little swapping around and A-B'ing to get a feel for the individual speakers. I was sort of disappointed that the Tonker Lite "failed" in one respect in that it wasn't really that close to the Tonker's tone.
Clearly that "F" amp wasn't suited to the tone of Fane Purple style speakers. Here's the thing. Hiwatt amplifiers and Fane's "Purples" were specifically designed to complement each other. You need that smooth upper end of the Purples to balance the extremely hi-fi top end response of a Hiwatt (or Triwatt).
