You are lookin' for a lynching, thinking of putting a boinger on a 10th!!!
Before destroying the integrity of that beautiful ride, think about your body positioning. It looks like your saddle height is pretty low and you could use that stem as a softball bat. I bet that if you put on a shorter / more upright stem, you would take a bunch of weight off your front end and the bike could float over the terrain better. (this has worked well for me as we've grown out of the '90s and I have gotten old!)
To each there own though, beautiful bike thanks for finally giving us the pics!
