Using a low capacitance cable can help preserve some of the highs and sparkle at reduced guitar volumes. There is also info on the net for doing a 50's style wiring on a strat, something that's most often seen on dual humbucker or dual P-90 instruments. That helps quite a bit as well and makes your controls a bit more interactive. One other way to approach it is to EQ your amp so when you're set at lower guitar volume your tone is still alive and what you're trying to achieve. Then when you roll up to full volume, yes, it will be way too bright, but you can easily dial down your tone control. For my ears I prefer some tone knocked off when I have a strat at full volume. It sounds fatter and is a more pleasant sound IMHO.
If you try a treble bleed and will be experimenting with different values of components, here's an idea that may be helpful for you.
When I was experimenting with different capacitors in a strat I temporarily soldered two wires in place and left the ends extend out from under the pick guard. Solder a couple of small alligator clips to the ends of the wires. That allows you to try different values easily.
