Hi Joker and welcome. I fear you may find getting narrow pinned blades very difficult as pin placement requires a rather beefy (by scrolling standards ) bit of blade stock to insert the pin at each end. I have had some limited success in narrowing the effective width of the active portion of my blades by applying a cheapy type sharpening stone to the rear of a blade while running the saw. Take care while doing this so as not to break the blade and check from time to time that you don't thin too much and make the blade too fragile. With care you may achieve a result. I have gotten my rubbish pinned blades down to nearly half of the original profile. remember that the gullets will be your weak points and leave enough meat behind them and you might get a result you can live with. Needless to say , take safety precautions , wear eye protection and keep fingers away and such. Good luck.
