More power to ya if you can make it work, pun intended. My thoughts go like so, not meant to be advice or otherwise, just sayin....
That motor already has ALL THE TORQUE you might need for get up and go. HP is great for speed, but no one was ever excited by horsepower. Only torque represents a net physical (as in "experience") change. If you want more get-up-and-go you need to strip off weight or get a Triumph Rocket III (hecause it has more torque than the SVTC) -- not sure how adding HP will add "zip" to a half-ton bike. Turbos and more likely engines that have them are not known for "low-end off-the-line" grunt.
Furthermore, consider a locomotive has 4000 HP -- yet not an impressive hole shot, am I right? A late model 13l semi-truck engine maybe has 1650 ft-pounds of torque and 550HP, ever beat one away from a stop light? What? Every single time? Without trying?
Just for fun, I had a ZX10R Special Edition -- that thing would go stupid fast, but it was UNIMPRESSIVE off the line. All that purposeful top speed and HP meant dopey tall, I'm gonna stall, gearing even in first gear. I leant it to a buddy of mine who loves Kawis and he said "that's disappointing, it is too 'single purpose' to be any fun"
You wanna go fast off the line? You need a light bike with heaps of torque. Or you could lose weight -- I dropped 30 pounds since I bought my SVTC in 2018 and I assure you the change in experience is dramatic.
When Aprilia made the Tuono they tuned the engine to make less HP and more torque, because fun. Same for the MT-10/R1 phenomenon, lower the HP and up the torque because fun.
I have ridden both these "hyper naked" bikes, and they will give the hooligan in us what we crave, and they delivered this by lowering the HP from the donor powerplant, not by increasing it.
As a final thought, my FJR1300 had way less torque and way less HP than my K1600 GTL, but the FJR pulled significantly harder from a standstill. Significantly.
