No, because in the usual NPN-PNP bipolar transistor version, all the current goes through the base-emitter junction.Could one make a 10 watt, Mhz-fast thyristor? Using a couple mosfets?

Can you share a schematic?A S-R latch in made in logic gates will latch much more quickly than a thyristor.
I suggest you read the article i linked in my first post, on thyristor-controlled rectifiers.An SCR or Triac, is either "On" or "Off",
and You don't get to choose when it turns "Off".
This would make a very poor "Current-Regulator".
i believe i mentioned it.We still don't know what you're trying to accomplish. Control the Current from what ?
To a load. Perhaps we're charging a super-capacitor, or powering a motor or LED. I'm skeptical that it matters.Control the Current to what.
as i mentioned, 10 watts. Let's say 2A at 5W. A max range would be 1A to 4A, at 5V to 10V.How much Current are we talking about ?, at what Voltage ?
I believe that's irrelevant. There are myriad applications requiring current control. Assume we're charging a super-capWhy does the Current need to be controlled ?
This thread concerns thyristor-controlled rectifiers, so it would be switched.Will the Current-Control be a fixed value ?,
or manually adjustable ?,
or controlled by some other outside signal ?
Yes, i know. That wasn't my question.an SCR or Triac will not do what You want,
