Your tight fit is the result of no wear which is very good of course. Since you have little or no wear to your BB shell bores, I have a suggestion.
Take a page from Cannondale and spec Loctite
#609 . Different Loctite formulas are spec'ed for different materials.
#609 is best for delrin/acytel to carbon....what you have. Apply the activator that they spec as shown below. Epoxy is more relevant when you have a bit more clearance which you don't have. As discussed epoxy is a suitable surrogate for carbon replacement due to wear because it bonds so effectively to the carbon matrix which is cousin polymer of epoxy. For a tight fit like you have, Loctite is suitable...Loctite even have formulas for slip and clearance fit also....but works especially nicely for a press or interference fit which doesn't accommodate epoxy as readily because it is more viscous. Basically all that is needed is a 'little' help to keep the bushings in place. With no help aka no adhesive, they are even money to shift and repetitive shifting equals wear over time.
