If it was me ...
This would be the point where I'd do it ... in the attempt to prove people right/wrong either way. Whether it works or not, its your mountain to climb and your project to make work or fail. Life is full of lessons learnt ... but this would be one hell of a fun lesson
I've built plenty of projects in a very cost-efficient manner (not cheap). One particular project of mine was dogged from the start, so-called experts saying shoehorning a supercharged SR20 into a 200B would not work! Well it worked well, and drove strong for 2 years before I sold it. I did the required brake upgrades and all too. On the ratio of fun per dollar spent ... it was very much worth every penny spent.
Then again ... One project that went wrong, was when I turboed a CBR1000 drag bike. It was just too hard to match a good turbo to the engine and tune it for decent times. The front wheel just would NOT stay down due to the boost ... despite having a 6.5" swingarm extension!!! In the end, I lost thousands of $ on it, but it was still fun to build and I had no regrets ... its only money! Sold the custom kit to a guy in Germany and swapped the rolling chassis for essential parts for my GSXR race bike ... so I got some money back! There is always someone who will buy your failed projects.
Doing the common upgrades and sharing the same mod stories is boring. Do something different or rarely attempted and have your own story to tell.
