Sorry, but I strongly doubt that - especially on the relatively flimsy Commando frame. If I interpret the pics correctly e.g. the drilling close to the ign coil IMHO compromises the downtube strength quite significantly, the other ones as well especially as they hit areas already prestressed by welding.

Whatever dude.
I don't think front down tubes are that stressed. Load should go through the backbone, not those little down tubes. They are just there to hang the engine.

First, I notice that this bike has the speedo on the left, and tach on the right. Is that standard positioning for these instruments for all Commandos, or were they mounted differently for left hand drive and right hand drive markets? Mine has the speedo on the right - and we drive left hand drive here, but that is where I mounted it after the rebuild; I can't remember whether I checked it or just put it there because it seemed logical to have it on that side.
Second, Skyguys and LAB exchanged notes about the original studs used to fix the carb manifold to the cylinder head. What is the engineering reason why the designers would have used studs in preference to bolts or screws? Are studs inherently stronger?
