This is the kind of question I try to avoid asking out of the gate as there must be a reason. But no response from OP so far makes it entirely appropriate. What the hell is the point of cutting off the power from time to time on your pedal board?
I can only think that it's a ham fisted solution to unwanted noise on the clean channel.
The trouble with blending fx DIY is the fact that some fx return their signal distinctly out of phase from the clean input. An out of phase effected signal blended with the clean sounds like the backside of Satan himself served up with a side of week old offal. There are multi channel blenders that account for this with a 180 switch on the return. Have at it.

And duly merged making for the mid thread nonsense. Shoulda just locked the duplicate OT.
Fender Boss to Fender Design Dept: "Let's have us a six string bass!"
FDD: "That's gonna look like a cartoon next to the rest of our stuff".

FDD: "Okay, you da Boss".
Step one is finding a builder. There's a few fine folk on here who might even volunteer a couple of evenings to slam them together.
Does the UK do "men's" sheds? They are everywhere here. Staffed by old geezers volunteering handyman assistance with space and tools for DIY projects.
Copying over the 410 specs to a pair of 210 is a trivial set of calculations.
You will need to find some bug eye covers or grill material and some more corners and feet.
You could put your speakers into a couple of custom 210 cabs for very little moola. Very easy to copy over the 410 porting and cab volume half and half for guaranteed result.
Join the club. The only way I can do it is with 'stupid' amounts of repetitive practice. Then when it's action time it sounds like someone else is playing the bass while I am doing the harmony. It's the very defintion of an out of body experience, well worth the effort. Yet I can't call myself a singing bassist as I can hardly even talk over bassing!
Beats me how that process is supposedly more complicated than a carnet. Give gummint two copies of your inventory, leave, come back with same inventory, boxes checked and on your way home.
If it's anything like NZ there will be a threshold value for collecting revenue on your total importation. Below the threshold they don't make you pay. Not sure if duty free booze and fags count against the total.
More watts make more loud until speaker until speaker say enough of this malarkey.
The power soak angle isn't applicable to a 500w solid state amp but there is a sort of corollary with some users of Genz Benz Streamliner amps.
It's possible to rewire 4 ohm load worth of parallel drivers to be 16 ohms instead. With a Streamliner driving hard into 16ohms it will do the hard driving tone with much less power coming out than normal.
Still no help to OP as the answer to the question is a simple hard no.
